Understanding Collisions and Energy Transfer

What happens during a collision?

• Kinetic energy is transferred between the colliding objects.

• Potential energy is created.

• Objects always come to a complete stop.

• No energy is transferred.

In the context of a tennis game, what causes the ball to move?

• The temperature of the court.

• The weight of the ball.

What is the effect of a faster-moving object in a collision?

• The object becomes stationary.

• Greater energy transfer and impact.

• The impact is smaller.

• Less energy is transferred.

What is likely to happen in a minor car accident?

• The cars explode.

• A large amount of force is involved.

In a game of billiards, what happens when a player uses a large force to hit a ball?

• The ball gains kinetic energy and moves down the table.

• The ball disappears.

• The ball loses energy and stops.

• The ball remains stationary.

What is the result of striking the cue ball lightly in billiards?

• A more forceful collision occurs.

• The balls fly off the table.

• The balls move faster and farther.

• The balls move slowly with a softer sound.

When is kinetic energy transferred from object to object?

• when those objects pass one another

• when the first object outweighs (weights more than) the second object

• when the first object has more potential energy than the second object

• when those objects collide
