Question

1) what is the relationship between tangential speed and angular speed?
2) You spin a billiards ball. does the edge of the ball or a place inside have the greater tangential velocity? what about angular velocity?
3) Imagine that someone is spinning a weight at the end of a spring so that the weight travels in a horizontal circle over the person's head. draw a top view of the weight going around the circle and draw the instantaneous velocity of the weight for four different points along the path?

Explanation / Answer

1) tangential speed = angular speed * radius of the curve

2) edge of the ball will have greater tangential velocity because value of radius will be greater than the radius of the point inside the ball. Angular velocity will remain same as both edge and inside point will cover same angular displacement.
