Impulse
When a force is applied to a body, it changes its momentum. The relation between the force and the change in velocity of a body is given by Newton’s 2nd law of motion in the following equation
- F = m X a = ma
Where F is the force applied, m is the mass of the body and ‘a’ is its acceleration. Now, we know that acceleration is rate of change of velocity
- Hence F = m X (v1 – v2)/t
- Or, F X t = m X (v1 – v2)
- i.e, Ft = m(v1 - v2)
