Explanation:
m = Mass of person
g = Acceleration due to gravity = 9.81 m/s²
d = Vertical height from the ground
F = Force = Weight = mg
Net work done would be
![W_n=W_{up}+W_{down}\\\Rightarrow W_n=Fdcos180+Fdcos0\\\Rightarrow W_n=-mgd+mgd\\\Rightarrow W_n=0](https://tex.z-dn.net/?f=W_n%3DW_%7Bup%7D%2BW_%7Bdown%7D%5C%5C%5CRightarrow%20W_n%3DFdcos180%2BFdcos0%5C%5C%5CRightarrow%20W_n%3D-mgd%2Bmgd%5C%5C%5CRightarrow%20W_n%3D0)
Hence, the work done on the person by the gravitational force is 0
