How to fall and miss the ground

One day Isaac Newton sat under a tree and watched an apple fall (or probably he didn’t, but let’s not dwell on that just now). He thought to himself “I wonder if an apple at the bottom of the tree feels a stronger pull towards the earth than an apple at the top of the tree?” – so perhaps the force something feels due to Earth’s gravity changes depending on how far away it is from the Earth. “Now I come to think of it,” he continued, “I’m hungry for apple pie,” and he went on his way, for all we know.
