Question

define angular displacement

Answer 1

The angular displacement is defined as the angle through which an object moves on a circular path. It is the angle, in radians, between the initial and final positions.

Answer 2

$\Large \text{Angular\: Displacement :-}$

❀ It is the angle described by the radius vector in a given time .

❀ It is defined as the ratio of the arc length of the circle travelled by the particle to the radius of the circle .

❀ It is a dimensionless quantity .

❀ It is a vector quantity .

❀ SI unit of angular displacement is radian .

❀ when a body rotates angular displacement lies along the axis of rotation .

❀ Angular displacement is positive, for anti clockwise rotation of body .

❀ Angular displacement is negative, for clockwise rotation of body .
