Forms of 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 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

What is 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 nuclear energy?

Back

Nuclear energy is the energy released during nuclear reactions, such as fission or fusion. It is the energy stored in the nucleus of an atom.

Front

How does light travel?

Back

Light travels in a straight line until it hits an object.

Front

What is refraction?

Back

Refraction is the bending of light as it passes through a new medium, such as from air into water.

Front

What is reflection?

Back

Reflection is the bouncing back of light when it hits a surface, such as a mirror.

What is an example of thermal energy in everyday life?

Back

An example of thermal energy is the heat produced by a hair dryer.

Front

What is an example of mechanical energy?

Back

An example of mechanical energy is pushing a shopping cart.

Front

What is an example of potential energy?

Back

An example of potential energy is a stretched rubber band.
