Energy Notes
Energy - Ability to do work or cause change.
Mechanical Energy - Energy an object has because of its motion or
position.
Potential Energy - Energy an object has because of its postion or shape.
Kinetic Energy - Energy an object has because it is moving.
Heat Energy - The energy related to the temperature of a substance.
Chemical Energy - Energy stored in chemical bonds.
Electromagnetic Energy - Energy which can travel through empty space as well as through
matter. Includes visible light, radio waves, X-rays, and others.
Nuclear Energy - Energy contained in the nuclei of atoms.
Wave - An oscillation that travels from one place to another with a certain velocity.
Heat Transfer - Energy will move from an object with a higher temperature to an area object of
lower temperature until the temperatures of the objects are equal.
Radiation - Transfer of energy through empty space.
Conduction - Transfer of heat from a warmer substance to a cooler substance through direct
contact.
Convection - Transfer of heat in a fluid through currents.
Conductor - A substance that conducts energy well.
Insulator - Does not conduct energy well.
Temperature - The measure of the average kinetic energy of the particles in a substance.
Specific Heat - The amount of heat necessary to raise the temperature of 1 kg of a substance 1
degree Celsius.
Electricity - The interaction of electric charges. (+) or (-)
- Like charges repel; Unlike charges attract.
Induction - The process of making an object electric or magnetic which is not normally electric
or magnetic by placing them in an electric or magnetic field.
Law of Conservation of Energy - Energy cannot be created or destroyed, it can only change
forms.
