Potential and Kinetic Energy

Front

What is Potential Energy?

Back

Potential Energy is the energy that an object possesses due to its position or condition. It is stored energy that can be converted into kinetic energy.

Front

What is Kinetic Energy?

Back

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

Front

Example of Potential Energy in everyday life?

Back

A book placed on a shelf has potential energy because of its height above the ground.

Front

Example of Kinetic Energy in everyday life?

Back

A car driving down the road has kinetic energy due to its movement.

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 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

How does height affect Potential Energy?

Back

The higher an object is, the more potential energy it has, because potential energy is directly proportional to height.

Front

How does speed affect Kinetic Energy?

Back

Kinetic energy increases with the square of the speed; if speed doubles, kinetic energy increases by four times.

Front

What type of energy does a compressed spring have?

Back

A compressed spring has potential energy due to its position and the force applied to compress it.
