| Question | Answer |
|---|---|
| energy source | an object that is the supplier of energy |
| energy receiver | an object to which the energy is transferred |
| wave | a continuous succession of pulses |
| transverse wave | a wave in which the motion of the material (medium) is perpendicular to motion of the wave |
| amplitude | the height of a wave crest. It is related to a wave’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 (medium) is parallel to the motion of the wave |
| pitch | the quality of a sound dependent mostly on the frequency of the sound wave |
| ultrasound | compression waves at much higher frequency that animals or humans can hear |
| 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 the seismic waves |
| S wave | a seismic wave that involves vibration perpendicular to the direction the wave is traveling: it arrives later than the P wave |
| L wave | a seismic wave that travels along the surface of the Earth: they are the last to arrive at a location |
| seismograph | an instrument that detects seismic waves |
| tsunami | a great sea wave produced by an earthquake (or volcanic eruption) on the ocean floor |
| mechanical energy | the energy transfer involved in an interaction that causes one or both objects to change position |
| constant speed | neither speeding up nor slowing down |
| linear relationship | the relationship between two quantities that, when plotted against each other on a graph, produce a straight line |
| slope | the tilt or slant of a straight line on a graph: the rise divided by the run |
| average speed | the distance traveled divided by the time taken |
| nonlinear 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 | ability to do work or cause change |
| potential energy | stored energy |
| kinetic energy | energy in motion |
