# Momentum

### What is Momentum?

## MOMENTUM

*Momentum is the quantity of motion of a moving object. It is a vector quantity that is the product of the MASS and the VELOCITY of an object.*

## LAW OF CONSERVATION OF MOMENTUM

**The law of conservation of momentum states that the momentum of an object before an event is equal to the total momentum after the event**

## EQUATION FOR MOMENTUM

**Momentum (kg m/s) = mass (kg) x velocity (m/s)**

## CALCULATING MOMENTUM

**If an object is at rest, and has a mass of 2000 kg, what it its momentum?**

An object at rest has a momentum of zero regardless of its mass. Therefore, the momentum of the object is ZERO
