Kinetic and Potential Energy

Front

What is Kinetic Energy?

Back

Kinetic Energy is the energy an object possesses due to its motion. It is calculated using the formula KE = 1/2 mv², where m is mass and v is 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 gravitational energy, calculated using PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What factors affect Kinetic Energy?

Back

Kinetic Energy depends on two factors: the mass of the object and its velocity. Increasing either mass or velocity increases the kinetic energy.

Front

What is the relationship between Kinetic and Potential Energy?

Back

Kinetic and Potential Energy are forms of mechanical energy. In a closed system, energy can be transformed from potential to kinetic and vice versa, but the total energy remains constant (Law of Conservation of Energy).

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 in action.

Front

What is an example of Potential Energy in everyday life?

Back

A book on a shelf, water stored in a dam, or a stretched rubber band are examples of potential energy.

Front

How does height affect Potential Energy?

Back

Potential Energy increases with height. The higher an object is positioned, the more gravitational potential energy it has due to its position relative to the ground.

Front

What is Chemical Energy?

Back

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

Front

How is energy converted in a glow stick?

Back

In a glow stick, chemical energy is converted into light energy when the chemicals inside react.

Front

What is the formula for calculating Kinetic Energy?

Back

The formula for Kinetic Energy is KE = 1/2 mv², where m is mass and v is velocity.
