Isaac Newton looks up at an apple. He is on planet earth and starts to think... which of his thoughts are true? (a) The force on the Earth is greater than the apple- because the Earth is more massive. (b) The force on the apple and the Earth are 0 because they aren't touching. (c) The force on the apple is greater than the Earth- because the Earth is more massive. (d) The force on the apple and the Earth are equa
