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 its velocity.

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

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

Give an example of Kinetic Energy.

Back

A moving car, a flowing river, or a flying baseball are all examples of kinetic energy.

Front

Give an example of Potential Energy.

Back

A book on a shelf, a drawn bow, or water stored in a dam are examples of potential energy.

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 Energy Transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as potential energy converting to kinetic energy.

Front

What is an example of energy transformation?

Back

A swing moving back and forth transforms potential energy at its highest point into kinetic energy at its lowest point.

Front

Can energy be created or destroyed?

Back

No, according to the law of conservation of energy, energy cannot be created or destroyed, only transformed or transferred.
