Description
Newton's law of gravitation hides how mass and distance each contribute, and a fraction alone gives little feeling for it. Gravity Force Lab lets you drag two bodies around, and changing mass or distance instantly changes the arrow length and force reading, which makes the inverse-square rule concrete.
A ruler marks the separation in meters, masses span a wide range, and readouts can switch to scientific notation.
Drag the distance: Move the masses closer or farther and watch the pull change.
Set each mass: Choose the masses separately and see that the forces are equal and opposite.
Readout format: Show decimals or scientific notation.
