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 and speed of the object.

Front

What is Potential Energy?

Back

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

Front

How does speed affect Kinetic Energy?

Back

Increasing an object's speed increases its kinetic energy.

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

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 type of energy does a stretched rubber band have?

Back

A stretched rubber band has potential energy due to its position.

Front

What type of energy does a moving car have?

Back

A moving car has kinetic energy due to its motion.

Front

What is Mechanical Energy?

Back

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

Front

What is an example of converting Potential Energy to Kinetic Energy?

Back

A roller coaster at the top of a hill has potential energy, which converts to kinetic energy as it descends.
