Looping the Loop
Consider a ball on a string making a vertical circle.
- Draw a free-body diagram of the ball at the top and bottom of
the circle
- Rank the forces in the two diagrams. Be sure to explain the
reasoning behind your rankings
- Find the minimum speed of the ball at the top of the circle
so that it keeps moving along the circular path
- What would happen if the speed was less than the
minimum?
- What would happen if the speed was more than the
minimum?
