Potential and Kinetic Energy

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 the square of its velocity. Formula: KE = 1/2 mv².

Front

What is Potential Energy?

Back

Potential energy is the stored energy of an object due to its position or state. It is often associated with gravitational energy, elastic energy, and chemical 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, calculated as PE = mgh (mass x gravity x height).

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 one form to another, but the total energy remains constant (Law of Conservation of Energy).

Front

Give an example of Kinetic Energy in sports.

Back

A volleyball player spiking a ball demonstrates kinetic energy as the ball is in motion due to the player's force.

Front

Give an example of Potential Energy in everyday life.

Back

A bowling ball sitting on a rack has potential energy due to its position above the ground.

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 mechanical energy.

Front

What is the formula for calculating Kinetic Energy?

Back

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

Front

What is the formula for calculating Potential Energy?

Back

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

Front

How does mass affect Kinetic Energy?

Back

Kinetic energy is directly proportional to mass. If the mass of an object increases, its kinetic energy increases if the velocity remains constant.
