| 16308483928 | 2 types of circular motion | rotation and revolution | 0 | |
| 16308505240 | Newton's first law | inertia; an object wants to continue moving in a straight line at a constant speed | 1 | |
| 16308561193 | Using Newton's first law, what can you conclude about an object moving in a circular path? | a force must be acting on the object | 2 | |
| 16308604019 | What is uniform circular motion? | moving in a circular path at a constant speed | 3 | |
| 16308650919 | Describe the velocity of an object traveling in a circle. | Because the object is traveling in a circle and its direction is constantly changing, its velocity is therefore constantly changing. It is accelerating. | 4 | |
| 16308733505 | Because an object moving in a circular path is accelerating, there must be a __________ acting on the object to make it go in a circle. | force | 5 | |
| 16308749249 | centripetal force | any force that causes and object to move in a circle , directed to the center of the circle, "center-seeking" force |  | 6 |
| 16308822597 | centripetal acceleration | always toward the center of the circle |  | 7 |
| 16308937256 | what are the two types of velocity in circular motion? | angular velocity | 8 | |
| 16308956971 | angular velocity (w) | rate of change of the angle; revolutions per minute; units are radians THE SAME FOR ANY POINT ALONG THE RADIUS |  | 9 |
| 16309018186 | tangential velocity (v) | the instantaneous velocity of a given point on the circumference of a circle; direction follows a line tangent to the circle |  | 10 |
