Energy Source The supplier of Energy.
Energy Reciever The object that gains energy transferred to it.
Wave A countinuous succession os pulses.
Transversal Wave A wave in which the motion of the material (Medium) is perpendicular to the motion of the wave.
Amplitude The Height of the wave crest. It is related to a waves's energy.
Wavelength The distance between identical points along a wave.
Frequency The number of waves Produced per unit time.
Compression (Longitudinal) Wave A wave in which the motion of the material (medum) is parallel to the direction of the motion of the wave.
Pitch The quality of a sound depends mostly on the frequency of the sound wave.
Ultrasound Compression of the wave at much higher frequency of the sound wave.
Fault A fracture in rock along which the rock masses have moved.
Earthquake A sudden motion or shaking of the earth.
P Wave A seismic wave that involves motion in the direction in which it is traveling; it is the fastest of seismic waves. It is the first to come.
S Wave A seismic wave that involves vibration perpendicular to the direction the wave is traveling; it arrives after the P Wave.
L Wave A seismic wave that travels along the earth; they are the last to arrive at a location.
Seismograph An instument that detects seismic waves.
Tsunami A great surface wave on the ocean produced by an earthquake or volcanic eruption on the ocean floor.
Mechanical Energy The energy transfer involved in an interaction that causes one of both objects to change position.
Constant Speed Neither speeding up nor slowing down.
Linear Relationship The relationship between two quantities that, when plotted against eachother on a graph, produce a straight line.
Slope A tilt or slant of a straight line on a graph; the rise devided by the run.
Average Speed The distance traveled devided by the time taken.
Non Collinear Relationship The relationship between two quantities that ,when plotted against each other on a graph, do not produce a straight line.
Velocity How fast an object is moving in a given direction.
Acceleration The change in velocity per unit time.
Energy -Causes interactions.-Ability to do work or cause change.
Potential Energy Stored Energy.
Kenetic Energy Energy in motion.
