Kinetic & 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 square of its velocity.

Front

What is Potential Energy?

Back

Potential Energy is the stored energy in an object due to its position or state. It is often associated with the height of an object above the ground.

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

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.

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 factors affect Potential Energy?

Back

Potential Energy depends on two main factors: height (h) and mass (m) of the object.

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 Kinetic Energy when speed doubles?

Back

If the speed of an object doubles, its Kinetic Energy increases by a factor of four, since KE is proportional to the square of the velocity.
