# Calculating Momentum

### Calculating Momentum

You will learn to apply the momentum equation to calculate the properties of a moving object.

Why does a moving car have **momentum**, but a stationary car does not? Pick all the options you think are correct.

You can select multiple answers

Momentum is sometimes defined as **mass in motion**. All objects have mass, so that must mean...

Compared to a car moving at $15\space m/s$ , the same car travelling at $30\space m/s$ has...

A car has a mass of $600\space kg$ and a velocity of $20\space m/s$ . The car has momentum with a magnitude of $12,000\space kg\space m/s$. Can you work out the formula that links mass, velocity and momentum?

Momentum can be calculated using the formula $Momentum=mass\times velocity$. This can also be written as $p=mv$.

Do you remember what the unit was that we used for momentum?

If a $60\space kg$ athlete is running with a velocity of $5\space m/s$, what is his momentum? Write your answer using the correct units for momentum.

If a $60\space kg$ athlete is running with a velocity of $3.5\space m/s$ , and a $58\space kg$ athlete is running with a velocity$4.5\space m/s$. Which has the most momentum?

The momentum of a car is $3\times 10{^3}\space kg\space m/s$ and the mass of the car is $1200\space kg$. How would you rearrange the formula for momentum to find the **velocity** of the car?

The momentum of a car is $3000\space kg\space m/s$, and it has a mass of $1200\space kg$. What is the **velocity** of the car?

A ball has a momentum of $10\space kg\space m/s$ and a mass of $2\space kg$. At what **velocity** is the ball moving?

The momentum of a car is $3\times 10{^3}\space kg\space m/s$ , and its velocity is $20\space m/s$. How would you rearrange the formula for momentum to find the **mass** of the car?

The momentum of a car is $20,000\space kg\space m/s$ , and its velocity is $20\space m/s$. What is the mass of the car?
