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 the square of its velocity. 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 can be gravitational, elastic, or chemical.

Front

What is Gravitational Potential Energy?

Back

Gravitational Potential Energy is the energy stored in an object as a result of its height above the ground. Formula: PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is Chemical Energy?

Back

Chemical Energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released or absorbed during a chemical reaction.

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.

How does energy transform in a glow stick?

Back

In a glow stick, chemical energy is transformed into light energy through a chemical reaction.

Front

What is an example of an object with kinetic energy?

Back

A tennis ball rolling across the court is an example of an object with kinetic energy.

Front

What is an example of an object with potential energy?

Back

A ball resting on the edge of a cliff has gravitational potential energy due to its height.

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy is affected by the mass of the object and its velocity. Increasing either will increase the kinetic energy.

Front

What is the difference between Kinetic and Potential Energy?

Back

Kinetic Energy is energy of motion, while Potential Energy is stored energy based on position or state.
