| When calculating angles in circular motion we use units of? | Radians |
| To convert from degrees to radians we multiply by | pi/180 |
| To convert todegrees from radians multiply by | 180/pi |
| Angular velocity is.... | the angle swept out by a radius per unit time, symbol w |
| The units for angular velocity is | rad/s |
| angular velocity = | angle change/time |
| angular velocity is also related to | the frequency of a system |
| angular velocity also = | 2 x pi x f |
| The time period of a system can be eqauted to | 1/f or 2pi/angular velocity |
| The linear speed of an object moving in a circle is related to | its angular velocity |
| linear speed = | radius x angular velocity |
| The force on an object moving in a circular path is also called | centripetal force |
| the size of a centripetal force is given by either | F=mv^2/r or mrw^2 |
| centripetal acceleration = | v^2/r or rw^2 |
