Gravity Force Lab analyze the gravitational force. Visualize the gravitational force that two objects exert on each other. Change properties of the objects in order to see how it changes the gravity force.

Sample Learning Goals
1. Relate gravitational force to masses of objects and distance between objects.
2. Explain Newton's third law for gravitational forces.
3. Design experiments that allow you to derive an equation that relates mass, distance, and gravitational force.
4. Use measurements to determine the universal gravitational constant.

Non-obvious controls: If you are doing a lecture demonstration, set your screen resolution to 1024x768 so the simulation will fill the screen and be seen easily.
