UNIT 2: IV. Momentum and Impulse

Momentum is a Vector quantity

• TRUE

• FALSE

Momentum is defined as the product of an object's:

• a) Mass and acceleration

• b) Force and time

• c) Mass and velocity

• d) Force and displacement

Impulse is defined as the change in:

The SI unit of impulse is the same as the SI unit of momentum.

• TRUE

• FALSE

In inelastic collision, KE increases.

• TRUE

• FALSE

A collision where total KE is conserved:

To maximize the impulse on an object, for a given force, you should:

• a) Decrease the time interval over which the force acts.

• b) Increase the time interval over which the force acts.

• c) Apply the force perpendicular to the direction of motion.

• d) Apply the force opposite to the direction of motion.

Which of the following has the greatest momentum if all are moving at the same speed?

• a) A tennis ball

• b) A baseball

• c) A bowling ball

• d) A ping pong ball

If net impulse is 0, change in momentum is:

An experiment designed to test impulse must measure both force and time.

• TRUE

• FALSE
