When an object is in circular motion, it need centripetal force.

1. Click the black ball and drag it up and down to change the radius r.

2. The torque acting on the red ball is zero since F is parallel to r.

3. Click the mouse button to pause, click it again to resume.

4. Click trace checkbox to trace the trajectory,
