The motion of a body is said to be circular if the body is always at a fixed
distance from a fixed point. The fixed distance is called radius and the fixed point
is called the centre of the circular path.
Motion Parameters of Circular Motion
Angular Position
Angular Displacement
Angular Velocity
Angular Acceleration

Angular Position (θ) the video (Click Here)
The angular position represents the orientation of a line with another line or
plane. Angular position is quantified by measuring how far the body is rotated
from the reference position.
The angular position is denoted by the symbol theta (θ) and can be measured in
degrees (°), radians (rads) or revolutions.
Angular Displacement (Δθ)
Angular displacement is defined as the change from the final position to the
initial position (Δθ = θf – θi). Angular displacement represents the angle formed
between the final position and the initial position of a rotating line.
As with linear displacement, angular displacement has a direction associated with
it.
Rotation in the clockwise direction is negative and rotation in the counterclockwise
direction is positive.
