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.
Linear Velocity Definition. The velocity or the linear velocity of an object is the time rate of change of linear displacement of the object. It is also defined as the speed of an object in a given direction. The linear velocity can be of two types depending on the motion in which it is evolved: Uniform Velocity: An object is said to be moving with a uniform velocity if it undergoes equal displacements in equal interval of time howsoever small these intervals may be.
