If I attach a tennis ball to a string and swing it in a circle of radius 4.8 meters so the ball completes one revolution every 2.2 seconds, then what is the speed of the ball (number of m/s)? The 2.2 second time to go around the circle is known as the period of the ball's motion, and the speed is often referred to as the tangential speed because the direction of its associated velocity is tangent to the circle.
