Gravity 101

Every particle repels every other particle with a force proportional to their masses and directly proportional to the distance between them.

Every particle attracts every other particle with a force proportional to their masses and inversely proportional to the distance between them. (correct)

Every particle attracts every other particle with a force proportional to their masses and directly proportional to the distance between them.

F = G m2 / r^2

F = G m1 m2 / r

F = G m1 m2 / r^2 (correct)

F = G m1 / r^2

The first test of the speed of light.

The first test of Einstein's theory of general relativity.

The first test of Coulomb's law of electrical forces between charged bodies.

The first test of Newton's law of gravitation between masses in the laboratory. (correct)
