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?
