Tangential Speed is equal to the instantaneous linear speed of the particle at any point on the curved path. Tangential speed at any point is equal to the multiplication of the radius of curvature and angular speed at a particular point on the curved path. Angular speed is defined as the time rate of change of the angular displacement along the curved path.
Rotational speed (sometimes called angular speed) is the. number of rotations per unit of time. â¢All parts of the rigid turntable rotate about the axis in the. same amount of time. â¢All parts have the same rate of rotation, or the same. number of rotations per unit of time.
