... The gravitational force F exerted by the Sun on a planet is given by: F=GMm/r2 The centripetal force for an object in orbit is given by: F = mv2/r The instantaneous velocity of an orbiting object is given by: v = 2πr/T So we have 4π2/T2 = GM/r3 and so r3 (4π2/GM) = T2 So our constant k = (4π2/GM) Re ...

Newton`s Laws
... According to Newton’s second law of motion, the acceleration of an object decreases if its mass increases. The snowball would slow down as it got bigger. Therefore, continually increased force would have to be applied to the snowball to maintain its starting speed. ...
