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 a wave 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
