Q
Angular velocity
A
Angular velocity is the rate of change of angle with respect to time
2
Q
Unit of angular velocity
A
The unit of angular velocity is the radian per second
rads / s
3
Q
Centripetal force
A
If a body is moving in a circle the force towards the centre needed to keep it moving in that circle is called centripetal force
4
Q
Centripetal acceleration
A
If a body is moving in a circle the acceleration it has towards the centre of the circle is called centripetal acceleration
5
Q
Period of an orbit
A
The time taken for a satellite to go once around the central body is called the periodic time or simply the period (T) of the orbit
