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 square of its velocity.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It can be gravitational, elastic, or chemical.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy stored in an object as a result of its height above the ground, calculated as PE = mgh (mass x gravity x height).

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

How does height affect Potential Energy?

Back

The higher an object is, the more gravitational potential energy it has, as it has the potential to fall and do work.

Front

What happens to Kinetic Energy when speed doubles?

Back

If the speed of an object doubles, its Kinetic Energy increases by a factor of four, since KE is proportional to the square of the velocity.

Front

What is an example of Kinetic Energy?

Back

A moving car, a rolling ball, or a flowing river are all examples of Kinetic Energy.

Front

What is 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 is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an energy transformation?

Back

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