Potential and Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a book on a shelf has potential energy because of its height.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. For example, a moving car or a rolling ball has kinetic energy.

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

At which point in a pendulum's swing is kinetic energy highest?

Back

Kinetic energy is highest at the lowest point of the swing.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

Front

Give an example of energy transformation from potential to kinetic energy.

Back

A swing moving back and forth is an example of energy transformation from potential energy at the highest point to kinetic energy at the lowest point.

Front

What type of energy does a moving skateboard have?

Back

A moving skateboard has kinetic energy.

Front

What type of energy is stored in a stretched rubber band?

Back

A stretched rubber band has potential energy.

Front

What is an example of an object with both potential and kinetic energy?

Back

A roller coaster at the top of a hill has potential energy, and as it descends, it gains kinetic energy.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground.
