What are the kinematic formulas?

The kinematic equations, also known as the equations of motion, describe the fundamental rules of motion for classical physics. They allow us to calculate various aspects of motion such as velocity, speed, displacement, time and acceleration. Here are the four kinematic equations:

1. Final velocity (v) equals initial velocity (u) plus acceleration (a) times time (t). In formula form: v = u + at

2. Displacement (s) equals initial velocity (u) times time (t) plus 1/2 times acceleration (a) times time squared (t^2). In formula form: s = ut + 1/2at^2

3. Final velocity squared (v^2) equals initial velocity squared (u^2) plus 2 times acceleration (a) times displacement (s). In formula form: v^2 = u^2 + 2as

4. Displacement (s) equals the average of initial and final velocities (u+v) divided by 2, times time (t). In formula form: s = (u+v)/2 * t

These formulas are used when acceleration is constant. Each formula includes four of the five kinematics variables: initial velocity, final velocity, acceleration, time, and displacement. If you know three of these, you can use the formulas to solve for the fourth.
