Question

Define angular displacement, angular velocity
and angular acceleration.​

Answer 1

Answer:

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.

the rate of change of angular position of a rotating body is angular velocity.

Angular acceleration is the time rate of change of angular velocity. In three dimensions, it is a pseudovector. In SI units, it is measured in radians per second squared, and is usually denoted by the Greek letter alpha.

Answer 2

Angular velocity

In physics, angular velocity refers to how fast an object rotates or revolves relative to another point, i.e. how fast the angular position or orientation of an object changes with time.

Formula; ω= θ/t

Angular Displacement:- 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.

Formula; θ = s/r  Unit; Rad/sec

Angular Acceleration;

Angular acceleration is the time rate of change of angular velocity.
