Law of universal gravitation
Every body in the universe attracts every other body with a force that, for 2 bodies, is directly proportional to the product of their masses and inversely proportional to the square of the distance separating them.
The force that an object exerts on a supporting surface (or, if suspended, on a supporting string), which is often, but not always, due to the force of gravity.
The intensity of an effect from a localized source spreads uniformly throughout the surrounding space and wakens with the inverse square of the distance.
Being without a support force, as in free fall
Any object that moves through the air or through space under the influence of gravity
the curved path followed by a projectile under the influence of constant gravity only
A projectile or small celestial body that orbits a larger celestial body
