Force falls with distance squared
Double the distance and the attraction becomes one quarter as strong. Hover the curve to move the test object.
Drag the test object or launch it sideways. Change mass and distance to see the orbit, vectors, and equations respond.
Gravity is not a hidden rope. It is the measurable way mass-energy shapes motion, usefully predicted by Newton and more deeply explained by Einstein.

F = G m₁m₂ / r²
Mass increases attraction linearly; distance weakens it quadratically.
The floor pushes upward on you, producing the sensation called weight.
