Potential and Kinetic 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. For example, an object at a height has gravitational potential energy.

Front

How does height affect Potential Energy?

Back

The higher an object is, the more potential energy it has. This is because potential energy is calculated as mass x gravity x height.

Front

What happens to Potential Energy when an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases, as it converts potential energy into kinetic energy.

Front

Give an example of Kinetic Energy in everyday life.

Back

A moving car, a running dog, or a thrown ball are all examples of kinetic energy.

Give an example of Potential Energy in everyday life.

Back

A book on a shelf, a drawn bow, or water stored in a dam are examples of potential 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 a roller coaster goes down a hill, potential energy converts to kinetic energy.

Front

What is the formula for calculating Kinetic Energy?

Back

Kinetic Energy (KE) = 1/2 x mass (m) x velocity (v)².

Front

What is the formula for calculating Potential Energy?

Back

Potential Energy (PE) = mass (m) x gravity (g) x height (h).

Front

What type of energy does a ball thrown in the air have at its highest point?

Back

At its highest point, the ball has maximum potential energy and minimum kinetic energy.
