# The Impulse-Momentum Equation

-> Mr. Stanbrough -> Physics -> Mechanics ->
Momentum -> this page

What is the relationship between impulse and momentum? It is simple -
and extremely powerful. The impulse-momentum equation says:
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".

Using the Impulse-Momentum Equation

You will need to be able to apply the impulse-momentum equation in
two general types of situations:

- Situations where you want the smallest possible force on an
object
- Situations where you want the largest possible velocity for an
object
