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 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

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 is stored in a compressed spring?

Back

The energy stored in a compressed spring is called Elastic Potential Energy.

Front

What is 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.

Front

What is an example of Potential Energy in everyday life?

Back

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

Front

How does height affect Potential Energy?

Back

The higher an object is, the more Potential Energy it has due to its position in a gravitational field.

Front

What is Mechanical Energy?

Back

Mechanical Energy is the sum of Kinetic and Potential Energy in an object.
