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 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 is the Law of Conservation of Energy?

Back

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is an example of Kinetic Energy?

Back

A moving car, a flowing river, or a thrown ball are all examples of Kinetic Energy.

Front

What is an example of Potential Energy?

Back

A book on a shelf, a stretched rubber band, or water stored in a dam are examples of Potential Energy.

Front

How is Kinetic Energy calculated?

Back

Kinetic Energy (KE) is calculated using the formula: KE = 1/2 mv², where m is mass and v is velocity.

Front

How is Potential Energy calculated?

Back

Gravitational Potential Energy (PE) is calculated using the formula: 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, assuming no energy is lost to air resistance.

Front

What is Mechanical Energy?

Back

Mechanical Energy is the sum of Kinetic and Potential Energy in an object that is used to do work.

Front

What is an example of energy transformation?

Back

When a roller coaster goes down a hill, Potential Energy is transformed into Kinetic Energy.
