Checkpoint: Energy

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

What happens to energy when a ball is dropped?

Back

When a ball is dropped, its potential energy is converted into kinetic energy as it falls.

Front

At which point on a roller coaster is gravitational energy the highest?

Back

Gravitational energy is highest at the highest point of the roller coaster.

Front

What is the relationship between height and gravitational energy?

Back

Gravitational energy increases with height; the higher an object is, the more gravitational energy it has.

Front

Is kinetic energy the energy of motion?

Back

Yes, kinetic energy is defined as the energy of an object due to its motion.

Front

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of potential energy?

Back

A rock held at the top of a hill has potential energy due to its height.

Front

What is an example of kinetic energy?

Back

A moving car has kinetic energy due to its motion.

Front

How does energy transfer occur?

Back

Energy transfer occurs when energy moves from one object to another, such as when a ball hits the ground and transfers energy to the ground.
