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

Some Examples of Energy
