Potential vs Kinetic Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy that an object possesses due to its motion. It depends on the mass of the object and the square of its velocity.

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or configuration. It is often associated with gravitational energy when an object is elevated.

Front

How is Kinetic Energy calculated?

Back

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

Front

How is Potential Energy calculated?

Back

Potential Energy (PE) is calculated using the formula PE = mgh, where m is the mass, g is the acceleration due to gravity, and h is the height above a reference point.

Front

What is an example of Kinetic Energy in everyday life?

Back

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

Front

What is an example of Potential Energy in everyday life?

Back

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

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 the relationship between Kinetic and Potential Energy in a pendulum?

Back

In a pendulum, Kinetic Energy is highest at the lowest point of the swing, while Potential Energy is highest at the highest points of the swing.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

Front

How does mass affect Kinetic Energy?

Back

Kinetic Energy is directly proportional to the mass of the object; doubling the mass will double the Kinetic Energy if velocity remains constant.
