... Newton also revised Kepler’s 3rd law to include the force of gravity. This allows us to find the mass of an object from the orbits of its satellites. For example, we can find the mass of Jupiter by calculating how long it takes one of its moons to go around it. (possible lab) We can even use a more ...
