Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy that an object possesses due to its motion. The faster an object moves, the more kinetic energy it has.

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It has the potential to be converted into kinetic energy.

Give an example of Potential Energy.

Back

A rubber band that is stretched out has potential energy because it is stored energy that can be released.

What happens to Potential Energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.

What is the relationship between Kinetic and Potential Energy?

Back

Kinetic and potential energy can be transformed into each other. For example, when a roller coaster goes down a hill, potential energy is converted into kinetic energy.

What is gravitational potential energy?

Back

Gravitational potential energy is the potential energy an object has due to its height above the ground. The higher the object, the more gravitational potential energy it has.

How does mass affect Kinetic Energy?

Back

The kinetic energy of an object increases with its mass. The formula for kinetic energy is KE = 1/2 mv², where m is mass and v is velocity.

How does height affect Potential Energy?

Back

The potential energy of an object increases with its height. The formula for gravitational potential energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

What is an example of energy transformation?

Back

When a stretched rubber band is released, the potential energy stored in the band is transformed into kinetic energy as it snaps back.
