Press the flag Space to change variables ---Variables--- G = Gravitational constant. M1 = Mass of first object M2 = Mass of second object ---Chart--- Blue = Total force Green = Total velocity Red = Velocity increase Cyan = Distance (between masses) ---Rules--- Total velocity may not exceed the greatest total force. Velocity may not be added without force. Velocity may not be removed (negative velocity simply adds velocity in the opposite direction and kinetic energy is traded for work energy) Gravity may add infinite energy to the scene. Mass does not affect velocity or work.
