Students are making a model of planetary motion. The students tie a tennis ball to a string. The string passes through a spool and is attached to a 1 kilogram mass.
The mass pulls down on the string as the students spin the tennis ball around the spool. If the students wish to change the model to show what would happen if the sun had a greater gravitational pull, what change should they make?
Spin the tennis ball at an increased speed
Replace the 1 kg mass with a 2 kg mass
Tie the tennis ball with a longer string
Change the spool to a longer one
