S.3 PHYSICS LESSON ONE : LINEAR AND NON LINEAR MOTION 03RD JANUARY 2024

Linear motion refers to the motion of a particle or an object in a straight line. The object moves along a path without any change in direction. The speed or velocity of the object may vary, but its direction remains constant. A common example of linear motion is a car traveling along a straight road.

On the other hand, nonlinear motion refers to the motion of a particle or an object in a curved or non-straight path. In nonlinear motion, the path of the object is not a straight line, and it may change direction at any point. The speed or velocity of the object may also vary.

Nonlinear motion can be divided into two main categories: uniform circular motion and accelerated motion. In uniform circular motion, the object moves in a circular path with a constant speed but changing direction. A common example of uniform circular motion is a satellite orbiting around the Earth.

In accelerated motion, the speed or velocity of the object changes with time. The object may accelerate in a straight line or in a curved path. A common example of accelerated motion is a car accelerating from rest and then coming to a stop.

Overall, the main difference between linear and nonlinear motion is the path of the object. In linear motion, the object moves along a straight path, while in nonlinear motion, the path of the object may be curved or non-straight.
