CALCULATIONS ON RELATIVE VELOCITY

In Advanced Level Maths, the equations of linear motion are:

1. Constant Acceleration:
- v = u + at
- s = ut + (1/2)at^2
- v^2 = u^2 + 2as

Where:
v = final velocity
u = initial velocity
a = acceleration
t = time
s = displacement

1. Uniform Motion:
- s = vt
- v = s/t

Where:
s = distance
v = constant velocity
t = time

1. Motion with Variable Acceleration:
- dv/dt = a(t)
- v = ∫a(t)dt
- s = ∫v(t)dt

Where:
a(t) is the acceleration function
v(t) is the velocity function
s(t) is the position function

These equations describe linear motion in one dimension. In two or three dimensions, vector equations are used to describe motion.
