# Momentum

## Momentum

**Momentum** is *a measure of the mass and velocity of an object*. A massive object and a tiny object can both have the same momentum, but the larger object must be travelling very slowly and the smaller object travelling really quickly.

## Momentum Equation

You need to recall and apply this equation. Example:

Calculate the momentum of an athlete of mass 60 kg running at a velocity of 10 m/s?

p = m x v

p = 60 x 10 = 600kgm/s

## 5Mark Questions

Momentum is an easy topic to create five mark questions.

This is because we already know a number of equations that include mass and velocity!

**Task**: Write down all the the equations in this topic that include mass and velocity so you can see how it fits into momentum.

- Calculate the momentum of a mouse of mass 500g scuttling through the grass at 3m/s
- Your answer should include: 1.5kgm/s / 1.5
- Calculate the mass of a mouse that has a momentum of 5kgm/s when it is scuttling through the grass at 4m/s. Give your answer in grams.
- Your answer should include: 1250g / 1250
- Calculate the velocity of a mouse of mass 250g scuttling through the grass with a momentum of 1 kgm/s.
- Your answer should include: 4m/s / 4
