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 factors affect Gravitational Potential Energy?

Back

Gravitational Potential Energy depends on the height of the object above a reference point and the mass of the object.

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 Gravitational Potential Energy?

Back

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

Front

How does height affect Potential Energy?

Back

As the height of an object increases, its Potential Energy increases because it has the potential to do more work due to gravity.

Front

What is an example of Kinetic Energy in everyday life?

Back

A moving car, a flowing river, or a person running are all examples of Kinetic Energy.

Front

What is an example of Potential Energy in everyday life?

Back

A book on a shelf, a drawn bow, or water stored in a dam are all 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, conserving the total mechanical energy.

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 falls, Potential Energy converts to Kinetic Energy.
