• mass

• velocity

In a(n) ______________, an object experiences a force for a given amount of time that results in a momentum change.

• collision

• acceleration

• free fall

• adhesion

A stationary object has a small amount of momentum.

• True

• False

Why is momentum considered to be a vector quantity?

• Momentum has to indicate both magnitude and direction.

• Momentum has to have a positive value.

• Momentum has to be calculated using speed.

• Momentum has a quantity but not a unit.
