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

When does an object have maximum kinetic energy on a roller coaster?

Back

An object has maximum kinetic energy at the bottom of each hill on a roller coaster.

Front

What happens to energy when a roller coaster goes up a hill?

Back

As the roller coaster goes up a hill, kinetic energy is converted into potential 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

Give an example of kinetic energy.

Back

A tennis ball rolling across the court is an example of kinetic energy.

Front

Give an example of potential energy.

Back

The pulled back string on an archer's bow is an example of potential energy.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy is converted into kinetic energy.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has potential energy due to its position.

Front

What type of energy does a moving car have?

Back

A moving car has kinetic energy because it is in motion.
