Example

Problem: A ball whirls around in a vertical circle at the end of a string. The other end of the string is fixed at the center of the circle. Assuming the total energy of the ball– Earth system remains constant, show that the tension in the string at the bottom is greater than the tension at the top by six times the ball’s weight.

FREE Expert Solution

In this problem, we'll use the conservation of energy and centripetal force to explain how the tension in the string varies.
