Potential and Kinectic 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 gravitational energy when an object is elevated.

Front

What is the formula for Kinetic Energy?

Back

The formula for Kinetic Energy (KE) is KE = 1/2 mv², where m is the mass of the object and v is its velocity.

Front

What is the formula for Gravitational Potential Energy?

Back

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

Front

How does height affect Potential Energy?

Back

The higher an object is positioned, the greater its Potential Energy, as it has more stored energy due to its elevated position.

Front

What happens to Kinetic Energy when speed increases?

Back

As the speed of an object increases, its Kinetic Energy increases exponentially, since it is proportional to the square of the speed.

Front

What type of energy does a skateboard have when it is rolling?

Back

A rolling skateboard has Kinetic Energy because it is in motion.

Front

What type of energy does a book on a shelf have?

Back

A book on a shelf has Potential Energy because it is elevated above the ground.

Front

Can an object have both Kinetic and Potential Energy?

Back

Yes, an object can have both Kinetic and Potential Energy at the same time, such as a roller coaster at the top of a hill that is about to descend.

Front

What is an example of converting Potential Energy to Kinetic Energy?

Back

An example is a diver jumping off a diving board; as they fall, their Potential Energy converts to Kinetic Energy.
