Kinetic and Potential 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. It is often associated with the height of an object above the ground.

Front

How does mass affect Kinetic Energy?

Back

Increasing an object's mass will increase its kinetic energy, as kinetic energy is directly proportional to mass.

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

At what point is Potential Energy greatest?

Back

Potential Energy is greatest at the highest point of an object's position.

Front

At what point is Kinetic Energy greatest?

Back

Kinetic Energy is greatest at the lowest point of an object's position, where it is moving the fastest.

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 velocity.

Front

What is the formula for Potential Energy?

Back

The formula for Potential Energy (PE) is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is the relationship between Kinetic and Potential Energy?

Back

Kinetic and Potential Energy are forms of mechanical energy. As one increases, the other decreases in a closed system.

Front

What is an example of Kinetic Energy?

Back

A moving car, a running athlete, or a flowing river are all examples of Kinetic Energy.
