Potential Energy = height*mass*gravity
the height is factually the height of the center of mass, which will be varied the same as the lowest of your feet. So when you hurdle, the height that you jump can be used to distinguish the alteration in height of your center of mass.In other words, it is inclined on the mass of the human, be contingent on how extraordinary the person can jump. Supposing a man is 80 kg and he can jump such that his center of mass rises 0.3 m in Earth's standard gravitational field. This sums to approximately 240 Joules of increase in GPE.
