| 12946915968 | tangential velocity | is the linear speed of something moving along a circular path |  | 5 |
| 12946915969 | centripetal force | a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving. |  | 6 |
| 12978006302 | centrifugal force | an apparent BUT FAKE force that acts outward on a body moving around a center, arising from the body's inertia. |  | 7 |

| 12946915986 | frequency | the rate at which something occurs or is repeated over a particular period of time or in a given sample; measured in Hertz, which is how many times per second something occurs |  | 15 |
