Testing gravity in Dovedale

We tested gravity on the way down from Dove Crag. The question was whether a heavier stone would fall faster than a lighter stone. So let's test it. The answer is that they hit the ground at the same time. You can explain it like this: Take two smaller equal sized stones and drop them. They are bound to hit the ground at the same time. Drop them right next to each other. It won't change anything. Now glue them together. They won't suddenly fall twice as fast because you have one block that is twice as heavy. You can split any large block into equal sized smaller blocks and work the process backwards. And this is what we do. We define gravitational field strength as the pull on a 1 kg block. It is force per unit mass. It is the PER that is important. Big blocks are made of smaller blocks but gravity acts PER 1kg block so all blocks fall at the same rate.
