- Gravitational Force
- Newton's Third Law
- Force Pairs
Visualize the gravitational force that two objects exert on each other. Adjust properties of the objects to see how changing the properties affects the gravitational attraction.
Sample Learning Goals
- Relate gravitational force to masses of objects and distance between objects.
- Explain Newton's third law for gravitational forces.
- Design experiments that allow you to derive an equation that relates mass, distance, and gravitational force.
- Use measurements to determine the universal gravitational constant.
