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 speed at which it is moving.

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 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 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

The higher an object is positioned, the greater its Potential Energy due to the increased height (h) in the formula PE = mgh.

Front

What happens to Kinetic Energy as an object slows down?

Back

As an object slows down, its Kinetic Energy decreases because it is directly proportional to the square of its velocity.

Front

What is an example of Kinetic Energy in everyday life?

Back

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

Front

What is an example of Potential Energy in everyday life?

Back

A drawn bow, a book on a shelf, or water stored in a dam are all examples of Potential Energy.

Front

What type of energy does a compressed spring have?

Back

A compressed spring has Elastic Potential Energy, which is stored due to its deformation.

Front

At which point in a pendulum's swing is Potential Energy highest?

Back

Potential Energy is highest at the highest points of the swing, where the speed is zero.
