Potential and Kinetic Energy Review

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. For example, a rock at the edge of a cliff 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

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has potential energy because it is stored energy that can be released when the band is let go.

Front

When is an object said to have the most kinetic energy?

Back

An object has the most kinetic energy when it is moving at its highest speed.

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 an example of kinetic energy in everyday life?

Back

An example of kinetic energy is a moving car or a person running.

Front

How does height affect potential energy?

Back

The higher an object is, the more potential energy it has due to the gravitational force acting on it.

Front

What is the relationship between potential and kinetic energy?

Back

Potential energy can be converted into kinetic energy and vice versa. For example, when a roller coaster descends, potential energy is converted into kinetic energy.

Front

What type of energy does a moving skateboarder have?

Back

A moving skateboarder has kinetic energy because they are in motion.

Front

What is an example of potential energy in a system?

Back

An example of potential energy is water stored in a dam, which can be released to generate electricity.
