Gravity

Gravity is one of only a few forces that exist in the universe.

In today's acitivity, you will use numbers from a simulation to discover how mass and distance affect gravitational force. You will need two resources to complete this task: 1. The paper that describes the activity. This paper was distributed during class and is posted as a pdf here. 2. The simulation called "Gravity Force Lab," prepared by the Physics Education Technology (PhET) group at the University of Colorado.
