or, sometimes "Impulse = Change in Momentum". In mathematical symbols, it can be written as:
or:
or:
The impulse-momentum equation can be easily derived from kinematics and Newton's Second Law. This equation is very closely related to Newton's Second Law - in fact, it is often called the "Impulse-Momentum form of Newton's Second Law".
You will need to be able to apply the impulse-momentum equation in two general types of situations:
