| Question | Answer |
|---|---|
| the rate of change in velocity of an object | Acceleration |
| the energy of an object moving along a curve around a fixed point, e.g., such as the moon traveling around the earth | Angular momentum |
| the force needed to create and maintain circular motion | centrifugal force |
| velocity increasing or decreasing steadily | constant acceleration |
| a scientist test in which there is only one variable | controlled experiment |
| a non-scientific word for acceleration that is decreasing; also called negative acceleration | deceleration |
| a force caused by air rubbing on an object | drag |
| the ability to do work | energy |
| a push or a pull | force |
| a force created by the rubbing of two objects against each other | friction |
| the force of the earth's pull on an object | gravity |
| the tendency of an object at rest to stay at rest and in object in motion to stay in motion | inertia |
| the energy of motion | kinetic energy |
| energy cannot be created or destroyed, only the change in its form, for example, kinetic energy can be changed to heat due to friction | law of conservation of energy |
