Potential & Kinetic Energy

Front

What is Potential Energy?

Back

Potential Energy is the energy stored in an object due to its position or state. It has the potential to do work when released.

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

What is the formula for Kinetic Energy?

Back

Kinetic Energy (KE) = 1/2 mv², where m is mass and v is velocity.

Front

What is the formula for Potential Energy?

Back

Potential Energy (PE) = mgh, where m is mass, g is acceleration due to gravity, and h is height.

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 unit is energy measured in?

Back

Energy is measured in Joules (J).

Front

What is an example of Potential Energy?

Back

A stretched rubber band or a book on a shelf.

Front

What is an example of Kinetic Energy?

Back

A car driving on the highway.

Front

How does energy transform in an electric pencil sharpener?

Back

Electrical energy is transformed into mechanical energy (motor), sound energy (noise), and thermal energy (heat).

Front

What is the relationship between Potential and Kinetic Energy?

Back

Potential Energy can be converted into Kinetic Energy and vice versa, depending on the object's position and motion.
