Gravitational Fields

School administrators generally do not allow physics classes to take field trips to other planets to study gravitational forces. And it is rather difficult to change the mass of the earth or the moon in an effort to see if such changes have an effect upon the gravitational force. But with this Interactive, changing the masses of planets and moons and the distance that separates them is a snap. And by doing so, a learner can discover the law of universal gravitation without ever leaving home or school.
