Types of Energy

Front

What is Electrical Energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is used to power devices and appliances.

Front

Define Kinetic Energy.

Back

Kinetic energy is the energy of an object due to its motion. The faster an object moves, the more kinetic energy it has.

Front

What is Potential Energy?

Back

Potential energy is the stored energy in an object due to its position or state. For example, a rock at the top of a hill has potential energy.

Front

Explain Mechanical Energy.

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object.

Front

What is Sound Energy?

Back

Sound energy is the energy produced by vibrating sound waves. It is a form of mechanical energy.

Front

What is Thermal Energy?

Back

Thermal energy is the energy that comes from the temperature of matter. It is the total kinetic energy of particles in an object.

Front

What is Radiant Energy?

Back

Radiant energy is the energy of electromagnetic waves, including light. It is the energy that travels through space.

Front

How does height affect Potential Energy?

Back

The higher an object is positioned, the more potential energy it has due to gravity. For example, a roller coaster at a higher point has more potential energy.

Front

What happens to Kinetic Energy when speed increases?

Back

As the speed of an object increases, its kinetic energy increases exponentially, calculated by the formula KE = 1/2 mv².

Front

Give an example of increasing Potential Energy.

Back

Pulling a wagon uphill increases its potential energy because it is being lifted against gravity.
