5.2 Circular motion

A constant net force perpendicular to the velocity of an object causes it to travel in a circular path. Such a force can be described as a centripetal force. For an object moving at a constant speed in a circle: Centripetal acceleration is given by:  and  = yields:  =...

The radian is a measure of an angle. It is defined as the angle subtended by a circular arc with a length equal to the radius of the circle. 2 radians is equal to 360°. The period of an object in circular motion is the time taken for one revolution, whereas the...
