Kinetic Energy

• Kinetic energy is active energy. It includes any form of energy where work is being done.

• Kinetic energy involves some type of movement, either of whole objects, particles within objects, or waves.

• Examples of kinetic energy include:

• Mechanical kinetic energy – energy in the form of moving objects.

• Thermal energy (heat) – energy in the form of movement of atoms and molecules in solids, liquids and gases.

• Radiant energy (radiation) – energy in the form of electromagnetic waves; light energy is a type radiant energy.

• Sound energy – energy in the form of waves caused by the vibration of particles within matter.

• Electrical kinetic energy – energy in the form of flowing electrons.

• We will look more closely at the different types of kinetic energy in a following lesson.
