A large moving ball collides with a small stationary ball. The momentum

of the large ball decreases, and the momentum of the small ball increases.

of the small ball decreases, and the momentum of the large ball increases.

of the large ball decreases, and the momentum of the small ball decreases.

does not change for either ball.

A billiard ball collides with a stationary identical billiard ball in a head-on collision. After the collision, which is true of the first ball?

It has one-half its initial velocity.

It moves in the opposite direction.

It maintains its initial velocity.

Many factors can affect what happens when balls collide. For example, the material the ball is made from, how hard the balls hit each other, whether both balls are moving, and the directions they are moving in. If two tennis balls are moving towards each other at the same speed what do you expect to observe (see)?

Both balls bounce off each other

One tennis ball will stop and the other will keep moving

One tennis ball will jump over the other ball

Which of the following would transfer more energy?

Raising ball 1 higher before release

Gently putting ball 1 down next to ball 2

Keeping ball 1 in the same place

Which of the following is true about what happens to energy when two balls collide?

The total amount of energy between the two balls stays the same.

The total amount of energy between the two balls becomes zero.

The total amount of energy between the two balls increases.

The total amount of energy between the two balls decreases.

What happens when two objects collide?

Energy is transferred from one object to another.

Energy is created and the objects move faster.

Which of the following collisions would cause a still object to move at the speed of the object that hit it?

a collision of a moving object with a still object of the same mass

a collision of a moving object with a bigger massed still object

a collision of a moving object with a lighter massed still object

When two objects of the same mass traveling at different speeds collide head on, both objects...

bounce backward and travel at their original speed.

change direction and move at their original speed.

When a ball is kicked harder at a slower moving ball the result is

the slower ball will return at a faster speed.

the slower ball with return at a slower speed.
