Which pulls harder gravitationally? the earth on the moon, or the moon on the
earth? Which accelerated more?


i know this is easy, but dont they pull the same, and accelerate the same?

If you used the formula F = G M1 M2 / R^2 tell me what does F represent

does F represent the force earth exerts on the moon or the moon exerts on earth or both??

Newton's Third Law gives you the answer to the first part - they pull at each other with equal force. For the second part, ask yourself if the same force is applied to two objects which will undergo the greater acceleration - the more massive object or the less massive object?

so they pull the same, but the moon will accelerate more because it has a smaller masss
