| A | B |
|---|
| Inelastic | Type of collision in which the objects lock together after the interaction |
| Power | Rate of doing work or using energy |
| Force | Push or pull |
| Geosynchronous | Type of orbit in which a satellite over the Earth's equator is synchronized with the Earth's rate of rotation |
| Kinetic | Energy associated with the speed of an object |
| Normal | Force that a surface exerts on an object |
| Fusion | Process in which 2 light nucei combine to form a heavier, more stable nucleus |
| Positron | Antiparticle of the electron |
| Potential | Energy associated with the position of an object |
| Aphelion | Maximum distance between a planet and the Sun |
| Centripetal | Force which produces circular motion |
| Quark | Subatomic particle that makes up protons and neutrons |
| Gravity | Force which holds planets in their orbits |
| Parallel | Circuit containing more than one path for electrons |
| Perigee | Minimum distance between a satellite and the Earth |
| Longitudinal | Type of wave in which the particles of the medium oscillate parallel to the direction of wave travel |
| Frequency | The number of waves that pass a given point each second |
| Current | Rate of charge flow |
| Period | Time for one complete revolution |
| Transverse | Type of wave in which the particles of the medium oscillate perpendicular to the direction of wave travel |
| Inertia | Object's resistance to a change in motion |
| Energy | Ability to do work |
| Acceleration | Change in velocity per unit time |
| Crest | Highest point on a wave |
| Fission | Process in which a heavy nucleus is split into 2 lighter, more stable nuclei |
| Series | Type of circuit in which the electrons have only one path to travel |
