Midterm Review 3 (2023)

Front

What type of energy increases when you compress a spring?

Back

Elastic potential energy is the energy stored in an object when it is compressed or stretched.

Front

What is the reaction force when a player throws a ball?

Back

The reaction force is the force of the ball impacting on the player.

Front

What is a good example of kinetic energy?

Back

A tennis ball rolling across the court is an example of kinetic energy, which is the energy of motion.

Front

What type of energy is stored when you stretch a rubber band?

Back

When you stretch a rubber band, you are storing potential energy.

Front

What is the reaction force when an archer shoots an arrow?

Back

The reaction force is the arrow's push against the bowstring.

Front

Define kinetic energy.

Back

Kinetic energy is the energy an object possesses 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 action and reaction forces?

Back

For every action force, there is an equal and opposite reaction force.

Front

What happens to elastic potential energy when a spring is released?

Back

When a spring is released, the elastic potential energy is converted into kinetic energy.

Front

Give an example of an object with potential energy.

Back

A car parked on a steep hill has potential energy due to its elevated position.
