Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

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

Front

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.

Front

Give an example of Kinetic Energy.

Back

A boy running around a track is an example of kinetic energy because he is in motion.

Front

Give an example of Potential Energy.

Back

A cup sitting on the edge of a table is an example of potential energy because it has the potential to fall.

Front

What happens to Potential Energy when an object falls?

Back

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

Front

What is the relationship between Kinetic and Potential Energy?

Back

Kinetic and potential energy are forms of mechanical energy. They can convert into each other; for example, when an object is lifted, it gains potential energy, and when it falls, that energy converts to kinetic energy.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the potential energy held by an object because of its height above the ground. It is calculated as weight times height.

Front

How does height affect Potential Energy?

Back

The higher an object is positioned, the more potential energy it has due to the gravitational force acting on it.

Front

What is the formula for Kinetic Energy?

Back

The formula for kinetic energy 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 gravitational potential energy is PE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.
