Energy transfers and waves

TermDefinition
Kinetic energy – the energy of an object that is due to the object’s motion.
Potential energy - the energy that an object has because of its position, shape, or condition of the object.
Compression - a wave that compresses the medium through which it is transmitted.
Media (medium) - a physical environment in which phenomena occur.
Mechanical energy - the amount of work an object can do because of the mass and velocity of an object.
Frequency -the number of waves produced in a given amount of time.
Mechanical force - forces that must travel through a medium.
Rarefaction the bending of a wave as the wave passes between two substances in which the speed of the wave differs.
Amplitude - the maximum distance that the particles of a wave’s medium vibrate from their rest position.
Wave - a periodic disturbance in a solid, liquid, or gas as energy is transmitted through a medium.
Pitch - a measure of how high or low a sound is perceived to be, depending on the frequency of the sound wave.
Transverse wave - a wave in which the particles of the medium move perpendicularly to the direction the wave is traveling.
Energy transformation - or energy conversion is the process of changing one form of energy to another.
Crest -The highest part of a wave.
Longitudinal wave - a wave in which the particles of the medium vibrate parallel to the direction of wave motion.
Trough -the lowest part of the wave between crests.
