Forces in physics refer to the interactions between objects that cause changes in their motion or shape. They are described using Newton's laws of motion and are crucial in understanding the behavior and motion of objects in the physical world. Here are some common types of forces in physics:

1. Gravitational Force: This force is responsible for the attraction between objects with mass. It is the force that keeps planets in orbit around the sun and objects grounded on the Earth.

2. Normal Force: The normal force is the force exerted by a surface to support the weight of an object resting on it. It acts perpendicular to the surface, preventing objects from falling through it.

3. Frictional Force: Friction is the resistance that opposes motion when two objects come in contact. It occurs due to the roughness of surfaces. Frictional force acts parallel to the surfaces in contact and can either be static (preventing motion) or kinetic (opposing motion).

4. Tension Force: Tension is the force exerted by a string, rope, or a similar object when it is pulled at both ends. It transfers force uniformly along its length and is responsible for maintaining the integrity of the object.

5. Applied Force: An applied force is the force exerted on an object by a person or object. It can be used to push, pull, or move an object in various directions.

6. Spring Force: When an elastic object, such as a spring, is compressed or stretched, it exerts a force according to Hooke's law. This force is directly proportional to the displacement from the object's equilibrium position.

7. Electrical Force: Electrical forces exist between charged particles, such as electrons and protons. Like charges repel each other, while opposite charges attract.

8. Magnetic Force: Magnetic forces result from the interaction between moving charged particles (currents) or magnetic fields. Magnets can attract or repel each other based on their poles.

9. Buoyant Force: Buoyant force acts on objects immersed in a fluid (liquid or gas) and is directed upward. It is responsible for the ability of objects to float in a fluid and is determined by the density of the fluid and the displaced volume.

These are just a few examples of forces in physics. Understanding and analyzing these forces is essential in the study of mechanics and other branches of physics, allowing us to predict and explain the behavior of objects in various scenarios.

Geometry is a branch of mathematics that deals with the study of the properties, relationships, and measurement of 2D and 3D shapes. In 2D geometry, we focus on the properties and relationships of flat shapes such as points, lines, angles, triangles, quadrilaterals, and circles.

Points are the basic building blocks of geometry. They define the position and location of objects in 2D space. A line is a straight path with infinite length that connects two points. An angle is the space between two intersecting lines or planes.

Triangles are 2D shapes that are formed by connecting three lines. They have three sides, three angles, and three vertices. Based on the length of their sides and angles, triangles are categorized into scalene, isosceles, and equilateral triangles.

Quadrilaterals are 2D shapes that have four sides and four vertices. The most common quadrilaterals are squares, rectangles, parallelograms, rhombuses, and trapezoids. These shapes have unique properties that define their symmetry, angles, and side lengths.

Circles are 2D shapes that are defined by a center point and a radius. They have an endless number of points on their circumference, and all of these points are equidistant from the center of the circle.

In 2D geometry, we use various tools and techniques to measure and calculate the properties of these shapes. For example, we use formulas to calculate the perimeter and area of triangles and quadrilaterals, and we use measurements to calculate the radius, circumference, and area of circles.

Overall, 2D geometry plays a fundamental role in many areas of math and science, including engineering, architecture, and physics. Understanding the principles and properties of 2D shapes helps us to better understand and analyze the world around us.

Five areas of physics worth remembering: Classical mechanics, energy and thermodynamics, electromagnetism, Relativity, and Quantum Mechanics. Classical mechanics - two main concepts worth knowing. The first is Newton’s second law: F= ma: Force equals mass times acceleration. If you apply a force to a fixed mass, it tells you how much acceleration you will get. And knowing acceleration which is the change in velocity, you can make predictions.

The second equation is the law of universal gravitation. it allows us to determine the motion of heavenly bodies. It says that the gravitational attraction between two bodies is the product of their masses divided by the distance between them squared, times a constant, called Newton’s gravitational constant.

Energy is not a vector like force or momentum, but it is just a number. Work is closely related to energy. It is force times distance traveled. Energy for most objects consists of kinetic energy plus potential energy. KE is the energy of motion, It is KE = ½ M V^2 – the more mass you have and/or the more velocity you have, the more energy you have.

Gravitational potential energy is expressed as PE = m g h – mass times the gravitational acceleration times the height. The total energy of an object is both Kinetic energy plus potential energy. Potential energy can take many forms. Gasoline or petrol has chemical potential energy. Important: Energy is always conserved. It is not created or destroyed. It only changes form.

Thermodynamics is the study of work, heat, and energy on a system. We showed energy is how much work you could do. But another form of energy is thermal energy. If a car is moving and you apply the brakes, the kinetic energy of the car gets converted to thermal energy, created by friction of the car’s brakes. Temperature is the average kinetic energy of atoms in a system. Thermal energy is the total kinetic energy of atoms in a system.

Entropy is a measure of disorder, or more accurately, the information required to describe the micro states of a system. The 2nd law of thermodynamics states that entropy of an isolated system can never decrease. Energy at lower entropy can do more work than energy at high entropy. The one way flow of Entropy seems to be the only reason we have a forward flow of time.

Electromagnetism is the study of the interaction between electrically charged particles. The essentials are in Maxwell’s equations. If you have a static object with a charge, it will affect only other charges. If you have a static magnet, it will affect only other magnets. It will not affect charges. But if you have a moving charge, it will affect a magnet. And if you have a moving magnet, it will affect a charge. The constants mu naught and epsilon naught are the permeability and permittivity of free space. These two constants determine the speed of light because they measure the resistance of space to changing electric and magnetic fields.

Special Relativity: Einstein presumed that the speed is the same in any frame of reference. This was one of the postulates.
The second postulate was principle of relativity - the laws of physics are the same for all observes who are moving at the same velocity relative to each other. Einstein showed that the only way these can be true is if time was not fixed, but was relative.

General relativity: Later Einstein showed using the same assumptions, there would be no way to tell if you were in an accelerating reference frame or standing stationary on earth. A flashlight beam will bend in gravity. But since light always takes the shortest path between any two points, this means that space-time itself is bending.

Quantum mechanics: Three principles are important. First by Max Planck, says that energy is not continuous, but is quantized. The amount of energy equals the frequency of the radiation times Planck's constant. Using this, Einstein later showed that a photon is both a wave and a particle.

The second is the Heisenberg's uncertainty principle: you cannot know both a particle’s exact position and it’s exact momentum at the same time. For a particle with mass, this means if you know exactly where a particle is, you don’t know how fast going. If you know exactly how fast it’s going, you don’t know where it is.
Schrodinger's equation: prior to measurement, quantum systems are in superposed states. This means that their properties can only be expressed as a wave function. A wave function simplified, is a set of probabilities. So in a hydrogen atom, you can’t know where to find the electron in advance. All you can know is the probability of where you might find it, if you measured it. Prior to measurement, all quantum systems are waves of probabilities. This is not a limitation of our measuring devices. It is a limitation of reality.

This chemistry video tutorial provides a basic introduction into the 4 states of matter such as solids, liquids, gases, and plasma. Solids have a definite shape and volume. Liquids have a definite volume but not a definite shape since they assume the shape of the container. Gases do not have a definite volume or shape. Solids and gases are fluid which mean they have the ability to flow. Plasma is an ionized gas that can conduct electricity. Solids and liquids have a relatively high density and gases have a low density.

This physics video tutorial explains the concept behind Newton's First Law of motion as well as his second and third law of motion. This video contains plenty of examples and practice problems. This video is useful for high school and college students studying physics.

Physics Basic Introduction and Final Exam Review:

Here is a list of topics on Newton's 3 Laws of Motion:
1. Newton's First Law of Motion - An object at rest will remain at rest unless acted on by an unbalanced force.
2. Second Part of Newton's First Law of Motion - An object in motion will continue in motion unless acted on by a net force
3. The net force is zero when an object moves with constant velocity
4. Newton's 1st Law of Motion Examples & Demonstrations - Ball rolling on a rough surface with friction such as a carpet vs a ball rolling on a smooth surface such as ice with very little kinetic friction.
5. Earth moves continually in space - lack of frictional forces
6. Newton's Second Law of Motion - Force = Mass times acceleration
7. Newton's 2nd Law of Motion - Force is proportional to mass and acceleration. Mass and acceleration are inversely related when the force applied is constant.
8. Newton's Third Law of Motion - Action Reaction Pairs. For every action force, there is an equal but opposite reaction force.
9. Newton's 3rd Law of Motion Examples - Astronaut throwing a ball in space. Fisherman throws a package out into see and experiences a recoil velocity.
10. Impulse equals force multiplied by time
11. Momentum - Mass in Motion. Momentum equals mass times velocity.
12. Scalar vs Vector Quantities - Magnitude and Direction
13. Impulse - Momentum Theorem
14. Variation of Newton's Second Law of Motion - Force is the rate of change of momentum
15. Applied Force, Frictional Force, Normal Force vs Weight Force
16. How to calculate Final Velocity / Speed Using Acceleration
17. Acceleration is the rate of change of velocity

Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

You can find other Wikipedia audio articles too at:

The history of Africa begins with the emergence of hominids, archaic humans and – at least 200,000 years ago – anatomically modern humans (Homo sapiens), in East Africa, and continues unbroken into the present as a patchwork of diverse and politically developing nation states. The earliest known recorded history arose in the Kingdom of Kush, and later in Ancient Egypt, the Sahel, the Maghreb and the Horn of Africa.
Following the desertification of the Sahara, North African history became entwined with the Middle East and Southern Europe while the Bantu expansion swept from modern day Cameroon (West Africa) across much of the sub-Saharan continent in waves between around 1000 BC and 0 AD, creating a linguistic commonality across much of the central and Southern continent.
During the Middle Ages, Islam spread west from Arabia to Egypt, crossing the Maghreb and the Sahel. Some notable pre-colonial states and societies in Africa include the Ajuran Empire, D'mt, Adal Sultanate, Warsangali Sultanate, Kingdom of Nri, Nok culture, Mali Empire, Songhai Empire, Benin Empire, Oyo Empire, Ashanti Empire, Ghana Empire, Mossi Kingdoms, Mutapa Empire, Kingdom of Mapungubwe, Kingdom of Sine, Kingdom of Sennar, Kingdom of Saloum, Kingdom of Baol, Kingdom of Cayor, Kingdom of Zimbabwe ...

⁣What is PBL?
Project Based Learning (PBL) is a teaching method in which students learn by actively engaging in real-world and personally meaningful projects.
In Project Based Learning, teachers make learning come alive for students.
Students work on a project over an extended period of time – from a week up to a term– that engages them in solving a real-world problem or answering a complex question. They demonstrate their knowledge and skills by creating a public product or presentation for a real audience.
As a result, students develop deep content knowledge as well as critical thinking, collaboration, creativity, and communication skills. Project Based Learning unleashes a contagious, creative energy among students and teachers.

And in case you were looking for a more formal definition...

Project Based Learning is a teaching method in which students gain knowledge and skills by working for an extended period of time to investigate and respond to an authentic, engaging, and complex question, problem, or challenge.

⁣Project-based learning in chemistry teaching is an instructional approach where students actively engage in real-world, hands-on projects that require them to apply their knowledge and skills in chemistry. Instead of traditional lecture-based teaching, project-based learning focuses on student-centered learning, where students take ownership of their learning and work collaboratively to solve problems or complete projects.

In chemistry, project-based learning can involve various activities such as conducting experiments, designing and building models, analyzing data, researching and presenting findings, and solving chemical problems. These projects are often interdisciplinary, integrating concepts from other subjects like physics, biology, and environmental science.

The goal of project-based learning in chemistry teaching is to provide students with a deeper understanding of chemical concepts and principles, as well as develop their critical thinking, problem-solving, communication, and collaboration skills. By working on authentic, real-world projects, students can see the relevance and application of chemistry in their everyday lives, making the learning experience more meaningful and engaging.

Some examples of project-based learning in chemistry teaching include:

1. Designing and conducting an experiment to investigate the effect of different variables on a chemical reaction.
2. Creating a model or simulation to understand the behavior of atoms and molecules.
3. Researching and presenting a project on the environmental impact of a specific chemical or chemical process.
4. Collaborating with peers to solve a chemical problem or design a solution to a real-world issue.
5. Analyzing and interpreting data from a chemical analysis or experiment to draw conclusions and make predictions.

Overall, project-based learning in chemistry teaching promotes active learning, critical thinking, and problem-solving skills, while also fostering creativity, collaboration, and communication among students.

⁣Topology is a branch of mathematics that deals with the properties and structures of spaces. In university mathematics, topology is typically studied as a subfield of analysis or geometry.

In topology, the focus is on studying the properties of spaces that are preserved under continuous transformations, such as stretching, bending, and twisting. The main objects of study in topology are topological spaces, which are sets equipped with a collection of subsets called open sets. These open sets satisfy certain axioms, such as being closed under finite intersections and arbitrary unions.

Topology is applied in various areas of mathematics, including analysis, geometry, algebra, and differential equations. It provides a framework for studying the properties of functions, continuity, convergence, compactness, connectedness, and many other concepts that are fundamental in mathematical analysis. In geometry, topology is used to study the properties of shapes and surfaces, such as their curvature, dimensionality, and topological invariants.

Topology also has applications in other fields, such as physics, computer science, and engineering. For example, in physics, topology is used to study the properties of space-time and the behavior of particles. In computer science, topology is applied in areas such as network analysis, data visualization, and algorithm design. In engineering, topology optimization is used to find the optimal layout or configuration of structures or systems to achieve certain performance criteria.

Overall, topology provides a powerful mathematical framework for studying the properties and structures of spaces, and its applications extend to various areas of mathematics and beyond.

Episode 1: Why Black Africans Were Historically Viewed As A Threat ?

The view that Black Africans were historically viewed as a threat is a complex issue with multiple factors. One significant factor is the history of colonialism and the European conquest of Africa. European powers colonised Africa for its natural resources, and the perception of Africans as "primitive" or "uncivilised" was used to justify the exploitation and subjugation of African peoples.

Another factor is the transatlantic slave trade, which saw millions of Africans forcibly taken from their homes and transported to the Americas as slaves. The dehumanization of Africans as property and the violent treatment they received from their slave owners further reinforced the perception of Africans as a threat.

Additionally, racism and prejudice against Black people have been pervasive throughout history and continue to be a problem today. This bias has often led to the assumption that Black people are inherently violent or dangerous, perpetuating the stereotype of the "angry Black man" or "aggressive Black woman."

In short, the perception of Black Africans as a threat has deep roots in history, including colonialism, slavery, and ongoing prejudice and discrimination. It is a complex issue that requires a nuanced understanding of history and culture to fully grasp.
Let's come together in reasonable dialogue to honor our ancestors and reclaim the world through an African lens. Join me as we delve into African history, culture, and worldview to better understand their relevance to our lives today. By sharing our thoughts and knowledge, we can pave the way for a new culture of awareness and reclaim our story. As the African Diaspora saying goes, "I am because we are, and we are because I am."

The median is a measure of central tendency that represents the middle value of a dataset when it is arranged in order. One way to estimate the median of a dataset is by using a cumulative curve.

A cumulative curve, also known as a cumulative frequency curve, is a graph that shows the cumulative frequency of a dataset. The x-axis represents the values of the dataset, and the y-axis represents the cumulative frequency. To create a cumulative curve, you first need to arrange the data in order, and then calculate the cumulative frequency for each value.

To estimate the median using a cumulative curve, you need to find the value where the cumulative frequency is exactly half of the total frequency.

For example, if you have a dataset of 10 values with a total frequency of 20, the median would be the value where the cumulative frequency is 10 (half of 20). By looking at the cumulative curve, you can find the value that corresponds to a cumulative frequency of 10, which is your estimate of the median.

In practice, if you have a large dataset, it may be more practical to use a cumulative frequency table rather than a graph. And if you have a continuous dataset, you can use a cumulative density function (CDF) instead of a cumulative frequency.
