Momentum Practice

Momentum is...

• the rate of transfer of velocity from one object to another

• the amount (quantity) of motion an object has.

• the time over which a force is exerted

• a numerical expression of the transfer of inertia

The equation for momentum is?

• momentum = force - mass

• momentum = acceleration / mass

• momentum = mass x acceleration

• momentum = mass x velocity

What is true about the relationship between mass and momentum.

• The less mass an object has, the more momentum it will have.

• a large object with a small velocity would have a small momentum

• an object will always have a large momentum if it has a large mass.

• an object with small mass could have a large momentum
