Momentum Intro Video

What units are used to express momentum?

• Kilograms meters per second

• Meters per second

• Kilograms per second

• Newton seconds

Which factor does NOT affect the momentum of an object?

• Mass of the object

• Velocity of the object

• Direction of motion

• Color of the object

According to the impulse-momentum theorem, what does impulse equal?

• Change in velocity

• Change in momentum

• Change in mass

• Change in energy

Why is it less painful to fall on a trampoline than on the ground?

• The trampoline reduces the force of impact

• The trampoline absorbs all the momentum

• The trampoline increases the time of impact

• The trampoline is softer

In a pool table example, what happens to the momentum of the first ball after collision?

• It remains with the first ball

• It is transferred to the second ball

• It is destroyed

• It is split between both balls
