Impulse is defined as the:

• Force applied over time

• Change in velocity over time

• Change in momentum over distance

• Mass multiplied by velocity

Which of the following statements about impulse is true?

• Impulse is always equal to the change in momentum.

• Impulse is equal to the initial momentum.

• Impulse is always negative.

• Impulse depends on time but not on force.

According to the law of conservation of momentum, in a closed system, the total momentum:

• Increases

• Decreases

• Remains constant

• Depends on the force applied

• Neither kinetic energy nor momentum

Which of the following is an example of an inelastic collision?

• Two billiard balls colliding

• Two magnets repelling each other

• Two cars colliding and sticking together

• Two electrons moving in opposite directions

In a perfectly elastic collision between two objects, what happens to their velocities after the collision?

• They both stop

• They reverse direction

• They remain the same

• They become zero
