All forms of energy fall under 2 categories:  Potential  Kinetic.

Potential PE NRG due to the position Ex: P.E.= height X mass X gravity Think of gravity as a force of approximately 10 m/s 2.

Energy is said to be the ability to do work. That means the ability to make something happen. By “happen” it means to make things move or change condition.

Kinetic and Potential Energy have many forms. 1. Mechanical Energy - Energy associated with motion or position.

Remember… all forms of energy are either kinetic or potential

Kinetic Energy Energy of motion

Potential Stored energy Positional energy – PE=heightXmassXgravity

Thermal Energy Definition: Heat. Vibration and movement of the particles in a substance Examples: geothermal, sun, fire **Friction produces heat nrg

Motion Energy Sometimes called Mechanical Energy Definition: Movement of objects and substances from one place to another. Examples: wind (air particles), transportation

Gravitational Energy Definition: Energy due to objects height above the earth’s surface. – Mass & height determine amount of PE Examples: marble top of ramp, water behind hydropower

Stored Mechanical Energy Definition: Energy stored in objects by applying force (push or pull). Examples: compressed springs and stretched rubber bands

Radiant (Light) Energy Definition: Electromagnetic energy that travels in transverse waves Examples: light, X rays, radio waves, sun

Chemical Energy Definition: Energy stored in the bonds of molecules. The energy that holds the particles together. Examples: biomass (wood), fossil fuels (oil), batteries, living organisms-plants/animals

Electrical Energy Definition: The movement of electrons, usually thru a wire. Examples: lightning Any electric appliances

Sound Energy Definition: Movement of energy through waves; vibration of air particles. Examples: music, speaking, noise, tree falling in forest…

Nuclear Energy Definition: Energy stored in the nucleus of an atom Example: fission-nuclear power plants, bombs fusion-energy produced in sun

Exit Ticket First and last name Draw the lab set up on page 2 or 3: marble, ramp, ½ cup Label as many forms of energy as you can. Point to exactly where they are in your picture.

QUIZ TIME! What type of energy cooks food in a microwave oven? ELECTROMAGNETIC ENERGY What type of energy is the spinning plate inside of a microwave oven? MECHANICAL ENERGY

QUIZ TIME! Electrical energy is transported to your house through power lines. When you plug an electric fan to a power outlet, electrical energy is transform into what type of energy? MECHANICAL ENERGY
