A
One radian is the angle subtended at the center of
the circle by an arc of length equal to the radius of the
circle.
2
Q
Period
A
The time taken by the body to complete the
circular path once
3
Q
ω = ?
A
ω = θ/t or 2π/T or 2πf
4
Q
Centripetal force
A
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
5
Q
Angular displacement
A
The angle through which an object
moves through a circle

A
v = ωr
7
Q
