Asked by anonymous
                what physical law/s were used during the "burns" of Apollo 13 to adjust its path/trajectory and get it home?  
I know the thrusters used Newton's third law. What else?

    action and reaction (force on exhaust equal and opposite to force on rocket.)
conservation of momentum
velocity of exhaust* mass of exhaust + velocity of vehicle * mass of vehicle after exhaust fired = original velocity of vehicle * original mass of vehicle
note velocity of exhaust negative as a rule
gravity G M Mearth/r^2 = Force on vehicle toward earth center

    Note do not forget centripetal acceleration m v^2/r
