Question	Answer
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
