Potential and Kinetic Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It depends on the mass and speed of the object, calculated using the formula KE = 1/2 mv².

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 gravitational energy, calculated using the formula PE = mgh.

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

How does mass affect Kinetic Energy?

Back

Kinetic Energy increases with mass. If two objects are moving at the same speed, the one with greater mass will have more Kinetic Energy.

Front

How does speed affect Kinetic Energy?

Back

Kinetic Energy increases with the square of the speed. Doubling the speed of an object increases its Kinetic Energy by a factor of four.

Front

What type of energy does a stretched rubber band have?

Back

A stretched rubber band has Potential Energy due to its position and the tension within it.

Front

What is an example of Potential Energy in everyday life?

Back

An example of Potential Energy is a book on a shelf. It has the potential to fall due to gravity.

Front

At what point does an object have maximum Kinetic Energy during free fall?

Back

An object has maximum Kinetic Energy just before it hits the ground, as it has converted all its Potential Energy into Kinetic Energy.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy an object possesses because of its height above the ground, calculated using the formula PE = mgh.

Front

What happens to Potential Energy as an object falls?

Back

As an object falls, its Potential Energy decreases while its Kinetic Energy increases, maintaining the total energy constant.
