Transformation of Energy Vocab
Energythe ability to cause change
Mechanical EnergyEnergy of motion AND position (sum of the potential and kinetic energy of an object)
Kinetic Energyenergy 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 EnergyEnergy cannot be created or destroyed, only transferred or transformed
Energy Chain
displays the flow of energy through a system
FrictionA force present when two objects come into contact
Thermal EnergyThe total K.E. of the molecules in a substance
HeatThe movement of thermal energy from one place to another
Temperature the average K.E. of the molecules of a substance.
Particle ModelShows the effects on molecules due to the increase or decrease of energy.
Conductionheat energy transfer through solids
Convectionthe transfer of heat energy through liquids and gases
Radiationthe transfer of heat energy through space
Wavedisturbances that transfer energy without moving matter
FrequencyThe time between two wave crests
AmplitudeThe distance from crest to trough
WavelengthThe distance between wave crests
Mechanical Wavewaves that need matter to transfer energy
Transverse Wave a wave that travels perpendicular to the disturbance
Longitudinal Wavea wave that moves parallel to the disturbance
Sound Waves/Sound EnergyMechanical waves that transfer energy to your air and are converted to noises in your brain
Electromagnetic Wavewaves that do not need matter to transfer energy
Some Examples of Energy
