Level 3: Potential and Kinetic Energy

Front

What is potential energy?

Back

Potential energy is the energy stored 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. The faster an object moves, the more kinetic energy it has.

Front

How does potential energy change to kinetic energy on a roller coaster?

Back

As a roller coaster climbs to the top of a hill, it gains potential energy. When it descends, that potential energy is converted into kinetic energy.

Front

What happens to kinetic energy when an object slows down?

Back

When an object slows down, its kinetic energy decreases.

Front

What type of energy is stored in a compressed spring?

Back

The energy stored in a compressed spring is called elastic energy.

Front

What is the relationship between speed and kinetic energy?

Back

The faster an object moves, the more kinetic energy it has.

Front

What type of energy does a moving skateboard have?

Back

A moving skateboard has kinetic energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object that is used to do work.

Front

Can potential energy be converted into other forms of energy?

Back

Yes, potential energy can be converted into kinetic energy and other forms of energy, such as thermal energy.

Front

What is an example of potential energy in everyday life?

Back

An example of potential energy is a stretched rubber band, which has energy stored due to its position.
