Radian is the angle subtended at the center of the circle by an arc of length equal to the length of the radius
Angular displacement is the angle trough which an object moves through a circle
Angular velocity is the rate of change of angulardisplacement
Angular velocity is the rate of change of angularposition of an object as it moves along a curvedpath
The unit of angular velocity is radians per second (rad/sec)
A body moving in a circular motion is moving in constant speed but the velocity changes because the direction changes. Therefore, it accelerates and experiencesa force towards the center.
Inertia - The tendency of an object to remain at rest or continue with uniform motion unless acted upon by a net external force.
Period is the time taken by the body to complete the circular path once
Frequency is the number of times that the body completes one revolution per second
Centrifugal Force is the apparent outwardforce experienced by a rotating body due to centripetal force
Centripetal Force is the resultant force acting on an object moving in a circle, always directed towards the center of the circle perpendicular to the velocity of the object
The magnitude of Centripetal Force depends on the mass of the object and its velocity squared
Centripetal acceleration is the acceleration of an object actingtowards the center of a circle when an object is in motion around the circle at a constantspeed
Angular Acceleration is the rate of change of angular velocity with respect to time
An object moving along a circular path is not in equilibrium and the resultant force acting on it is centripetal force
A particle undergoing uniform circular motion has zero linearmomentum but non-zero angularmomentum
