Energy Notes and study Guide:
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
foods and fuels are sources of chemical potential energy
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.
Kinetic becomes potential when an object increases it’s hight and loses speed.
Potential becomes kinetic when an object loses height and gains speed.
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
