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
