Please help me figure out what this graph is called!!! My teacher made us copy down this graph which represents both the kinetic energy and gravitational potential energy of an mass due to its its distance away from the centre of the earth. The graph takes the form of a gravitational potential energy graph with the reference point at infinity. He never told us what the graph was called and now i'm finding difficulty understanding how it works, could someone please tell me what the graph is called so i could research about it... If you could also explain it that would be awesome haha.
