Experiment: Uniform Circular Motion
... What Causes Uniform Circular Motion If you tie a washer to a string, you can swing it around over your head. What keeps it going in a circle? You can feel the tension in the string. The string is providing an inward force toward the center of the circular orbit of the washer. Meanwhile the velocity ...
