Potential and Kinetic Energy Practice

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 held at a height has potential energy because of its position above the ground.

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. For example, a rolling ball has kinetic energy.

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 happens to energy when a roller coaster goes down a hill?

Back

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

Front

Can energy be created or destroyed?

Back

No, energy cannot be created or destroyed; it can only be converted from one form to another.

Front

What type of energy does a baseball have when held by a pitcher?

Back

A baseball held by a pitcher has potential energy.

Front

What type of energy does a flashlight have when it is turned off?

Back

A flashlight that is turned off has potential energy.

Front

What is the relationship between mass and kinetic energy?

Back

The greater the mass of an object moving at the same speed, the greater its kinetic energy.

Front

What is an example of converting potential energy to kinetic energy?

Back

An example is a diver jumping off a diving board; as they fall, their potential energy converts to kinetic energy.

Front

What is an example of converting kinetic energy to potential energy?

Back

An example is a swing going up; as it rises, kinetic energy converts to potential energy.
