Whilst perusing a wikipedia article about arboreal movement I came across a line which implied that
"As an animal moves up an inclined branch, they must fight the force of gravity to raise their body, making movement more difficult."
I interpreted this (possibly incorrectly) that the author was saying gravity becomes more of a problem the higher you climb. This seemed at odds with my elementary school learning.
Does gravity exert a greater force on an object the further it gets from a larger body or is that pressure simply the result of atmospherics? Surely, all things being equal, climbing 1 metre above the ground is the same gravitational force as climbing 100 metres above ground?
Note: I had also assumed that at n distance gravity exerts a continually weakening effect which allows travelling bodies to slingshot into the gravitational orbit of a body and then back out again as gravity is weaker the further away from a body.
