4.PS3.2 - 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 ball at the top of a hill 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

At what point does a roller coaster have the most potential energy?

Back

At the highest point on the track, where it has not yet started to descend.

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

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses because of its height above the ground.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in objects that can be stretched or compressed, like springs or rubber bands.

Front

What is chemical potential energy?

Back

Chemical potential energy is the energy stored in the bonds of chemical compounds, like food or fuel.

Front

How can you identify an object with kinetic energy?

Back

An object with kinetic energy is one that is moving, such as a rolling ball or a flying bird.

Front

What is the relationship between potential and kinetic energy?

Back

Potential energy can be converted into kinetic energy and vice versa, depending on the object's motion and position.

Front

What is an example of an object with gravitational potential energy?

Back

A book placed on a shelf has gravitational potential energy due to its height.
