Energy and Waves

Front

What is light energy?

Back

Light energy is a form of energy that travels in waves and is part of the electromagnetic spectrum. It is visible to the human eye and is responsible for sight.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. An example is a ball rolling down a hill.

What do waves transfer?

Back

Waves are a method of transferring energy from one place to another without transferring matter.

Front

What is energy?

Back

Energy is the ability to do work or cause change.

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a point in one second, measured in Hertz (Hz). Higher frequency means more energy.

Front

What is the electromagnetic spectrum?

Back

The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light, radio waves, and X-rays.

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 gravitational potential energy.

Front

What is kinetic energy?

Back

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

Front

What is sound energy?

Back

Sound energy is a form of energy produced by vibrating sound waves that travel through a medium such as air, water, or solids.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.
