A puck travels in a circular path on a frictionless table, propelled by a string pulling from the center of the circle (position is shown in meters and time is shown in seconds). You may adjust the mass (10 g < m < 500 g), the speed (1 m/s < v < 50 m/s), and/or the radius (0.5 m < r < 3.5 m). The tension is displayed on the screen. Restart.

How does the tension in the string depend upon the mass, the speed of the block, and the radius of the circle?

1. If you only vary the mass, how does the tension change?
2. If you only vary the velocity, how does the tension change?
3. If you only vary the radius, how does the tension change?
