Forms of Energy

Front

What is potential energy?

Back

Potential energy is the energy that is stored in an object due to its position or state. It can be converted into kinetic energy when the object is in motion.

Front

What is electricity?

Back

Electricity is the energy of moving electrons, which can be harnessed to power devices and perform work.

Front

Front

What type of energy is light?

Back

Light is a form of electromagnetic energy.

Front

Can energy be completely used up?

Back

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, dependent on its mass and velocity.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object that is used to do work.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, related to the motion of particles.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves, which can be heard when they reach a listener's ear.

Front

What is nuclear energy?

Back

Nuclear energy is the energy stored in the nucleus of an atom, which can be released during nuclear reactions.
