The equation of Angular velocity is: $\omega$ = $\frac{\theta}{t}$ radians/sec. 4. The linear velocity could be constant since the object could be travelling with constant speed without changing its direction. The angular velocity could not be constant since the body is constantly changing its direction.
the angular velocity is defined as the rate of change of angular displacement and is a vector quantity which specifies the angular speed or rotational speed of an object and the axis about which the object is rotating.ngular Velocity Formula. dt is change in time t. Angular Velocity Formula is given by. t is the time taken. The linear Velocity and angular velocity is given by the formula. r is the radius of circular path.
