Forms of Energy
What is Matter? Matter is defined as anything that has mass and occupies space Anything you can hold or touch is matter Examples: Books, desks, phones, and so is air, why air? Things that are not matter: Light, sound, and electricity These things are not matter because they have no mass or volume
Energy Energy is the ability to change or move matter If I were to move a desk, it would require energy Our bodies require energy to function, we obtain this energy from food Without energy, living organisms would not survive
Forms of Potential Energy Gravitational Potential Energy Elastic Potential Energy Chemical Energy Nuclear Energy
Gravitational Potential Energy The energy that results from its position above the ground Any system of two or more objects separated by a distance contains gravitational potential energy This results from the gravitational attraction between the objects
Elastic Potential Energy The energy stored in any type of stretched or compressed elastic material Examples include a clock spring, bungee cord, and rubber band What would happen if I had a rubber band stretched out and then released it? What happens when a compressed spring is released?
Chemical Energy The energy stored within atoms and molecules that can be released when a substance reacts
Nuclear Energy Energy that comes from the splitting of an atom, or fusing two atoms together This is an energy stored by the forces holding subatomic particles together in the nuclei of atoms
Forms of Kinetic Energy Radiant Energy Thermal Energy Sound Electrical Energy
Radiant Energy AKA light energy or electromagnetic energy This is electromagnetic energy that travels in transverse waves An example of this is solar power
Thermal Energy This is energy that comes from heat and the vibration of atoms and molecules Examples include geysers and coal burning Another example is boiling water As the water heats up the molecules began to vibrate and have an increase in velocity. In return this cause the water to heat up
Sound Sound is the movement of energy through substances in longitudinal waves Examples include echoes and music
Electrical Energy This is another term for electricity Our homes are powered by electricity This results from the flow of charged particles through wires or other conducting materials
