Gravity Force Lab: Basics
Gravity Force Lab: Basics is an interactive sim. It changes as you play with it.
The Play Area has a blue sphere labelled m1 and a red sphere labelled m2 and each sphere is held in place by a robot. A force vector starts at the center of each sphere and points directly at the opposite sphere. Spheres can be moved closer or further from one another, and the mass of each sphere can be increased or decreased. A ten-meter ruler can be moved around to take measurements. In the Control Area there are checkboxes and buttons to display force values with or without scientific notation, set the spheres to a constant size, and to reset the sim.
Currently, force on m1 by m2 is of equal magnitude and pointing directly opposite to the force on m2 by m1.
- Force vectors are tiny at 33.3692 newtons.
- mass 1 and mass 2 are somewhat close to each other, exactly 4000 meters apart.
- Mass of mass 1 is 2000000000 kilograms, comparable to mass 2 at 4000000000 kilograms.
- Robots pulling a tiny bit keeping spheres in place.
Move spheres or change their mass to begin observations.
