Energy Transfer and Collision

Front

What are the two types of energy released into the air during a collision?

Back

Heat and sound.

Front

What happens to the block when the wrecking ball is pulled back further and let go?

Back

The block moves further.

Front

Why does the block move forward after the wrecking ball collides with it?

Back

The contact force from the wrecking ball made the block move forward and kinetic energy is transferred from the ball to the block.

Front

What happens to the speed of the wrecking ball when it is pulled back further?

Back

It hits the block faster because it has more potential energy to convert to kinetic energy.

Front

What is transferred from coin 1 to coin 2 during a collision?

Back

Kinetic energy is transferred from coin 1 to coin 2.

Front

Define kinetic energy.

Back

Kinetic energy is the energy an object has due to its motion.

Front

Define potential energy.

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is the relationship between potential energy and kinetic energy in a swinging pendulum?

Back

As the pendulum swings down, potential energy is converted into kinetic energy.

Front

What is a contact force?

Back

A contact force is a force that acts at the point of contact between two objects.

Front

What happens to energy during a collision?

Back

Energy is transferred from one object to another during a collision.
