Energy Notes:
Basic forms of energy:
potential - stored energy
gravitational - stored by gravity and height
elastic - stored by stretching/compressing certain materials
chemical - stored in bonds between atoms of foods and fuels
nuclear - stored in the nucleus of atoms
kinetic - energy of motion
thermal - vibration of atoms in a substance due to temperature
sound - vibration of atoms in air
electric - flow of electric current (electrons) through wires
Mechanical - total of KE and PE in any system of parts
Radiant - light energy, electromagnetic radiation
light (visible, infrared, ultra violet
microwaves
X-rays
radiowaves, etc.
Energy Transformations
conversion of one form of energy into another.
any form of energy can be transformed into any other - though it may require more than one step.
Conservation of Energy
during any energy transformation - the total energy does not change
total energy before the transformation equals the total energy after the transformation
energy is neither created nor destroyed
