Question 2 (1 point) 
What does Newton's third law say about why momentum is conserved in collisions?

Question 2 options:

Equal forces act in equal times, so the change in momentum for both objects must be equal.

Unequal forces act for unequal times, so the change in momentum for both objects must be unequal.

Equal forces act for unequal times, so the change in momentum for both objects must be equal.

Unequal forces act for unequal times, so the change in momentum for both objects must be equal.

Question 3 (1 point) 
What makes some collisions elastic and others inelastic?

Question 3 options:

If the collision involves bouncing, it is elastic.

If the collision involves sticking together, it is elastic.

If there is no loss of kinetic energy in the collision, it is inelastic.

If there is energy lost in the collision to sound, heat, etc., the collision is inelastic.

Question 4 (1 point) 
How is momentum conserved in a system in which two satellites connect?

Question 4 options:

The one satellite has all the momentum before they connect, and then afterwards they share it.

Both satellites have momentum before they connect, and afterwards they have less momentum.

Both satellites have momentum before they connect, and afterwards they have more momentum.

Momentum is not conserved when the two satellites connect.

Question 5 (1 point) 
How is momentum conserved when the big rolling ball hits the smaller rolling ball?

Question 5 options:

The big ball gives all of its momentum to the small ball.

The small ball had no momentum before the collision, and afterward it has all the momentum.

The big ball transfers some of its momentum to the small ball, but it keeps going forward, too.

Momentum is not conserved when the two balls collide.
