Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy an object has due to its motion. It depends on the mass of the object and its velocity.

Front

What is Potential Energy?

Back

Potential energy is stored energy or energy due to an object's position. It can be converted into kinetic energy.

Front

What is Mechanical Energy?

Back

Mechanical energy is the sum of kinetic and potential energy in an object.

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 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

At what point does an object have maximum potential energy?

Back

An object has maximum potential energy at its highest point.

Front

At what point does an object have maximum kinetic energy?

Back

An object has maximum kinetic energy at its lowest point or when it is moving the fastest.

Front

What is an example of Kinetic Energy?

Back

A moving car, a running athlete, or a flowing river are examples of kinetic energy.

Front

What is an example of Potential Energy?

Back

A drawn bow, a rock at the top of a hill, or water stored in a dam are examples of potential energy.
