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.
When an object spins in a circle, the distance it travels in one revolution is the. circumference of the circle, 2 r. The time it takes for one revolution is the. period, T. Therefore, speed or v. where v is called the linear or tangential speedbecause at any given time, the. velocity is tangent to the circle as shown in the diagram. Although the velocity. is constant in magnitude (speed), it is always changing direction.
