E N D
Energy • the ability to cause change
Mechanical Energy • Energy of motion AND position (sum of the potential and kinetic energy of an object)
Kinetic Energy • energy of movement as a result of speed and mass.
Energy Transfer • the same form of energy being passed from one object to another
Energy Transformation • energy changing from one form to another form
Law of Conservation of Energy • Energy cannot be created or destroyed, only transferred or transformed
Energy Chain • displays the flow of energy through a system
Friction • A force present when two objects come into contact
Thermal Energy • The total K.E. of the molecules in a substance
Heat • The movement of thermal energy from one place to another
Temperature • the average K.E. of the molecules of a substance.
Particle Model • Shows the effects on molecules due to the increase or decrease of energy.
Conduction • heat energy transfer through solids
Convection • the transfer of heat energy through liquids and gases
Radiation • the transfer of heat energy through space
Wave • disturbances that transfer energy without moving matter
Frequency • The time between two wave crests
Amplitude • The distance from crest to trough
Wavelength • The distance between wave crests
Mechanical Wave • waves that need matter to transfer energy
Transverse Wave • a wave that travels perpendicular to the disturbance
Longitudinal Wave • awave that moves parallel to the disturbance
Sound Waves/Sound Energy • Mechanical waves that transfer energy to your air and are converted to “noises” in your brain
Electromagnetic Wave • waves that do not need matter to transfer energy
