Potential and Kinetic Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It depends on the mass of the object and the speed at which it is moving.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. For example, a ball held at a height has potential energy.

Front

How does speed affect Kinetic Energy?

Back

The faster an object moves, the more kinetic energy it has. Kinetic energy increases with the square of the speed.

Front

What two factors affect Kinetic Energy?

Back

Mass and speed are the two factors that affect kinetic energy.

Front

What is the formula for Kinetic Energy?

Back

The formula for Kinetic Energy (KE) is KE = 1/2 mv², where m is mass and v is speed.

Front

What is an example of Potential Energy?

Back

An example of potential energy is a stretched rubber band or a rock at the top of a hill.

Front

At which point is Potential Energy greatest in a roller coaster?

Back

Potential energy is greatest at the highest point of the roller coaster.

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 the relationship between Kinetic and Potential Energy?

Back

Kinetic and potential energy can transform into each other. For example, when a ball is thrown, potential energy converts to kinetic energy as it moves.

Front

What type of energy does a moving car have?

Back

A moving car has kinetic energy.
