The Example: water tank.
Water is rising in the tank vertically or head then the kinetic energy is also rising.

ME= PE +KE.
In case vertically raised body ( I.e v= 0).
KE=0 j.
Therefore ME = PE.
Another case;
Vertically falling body about to touch the ground ( I.e v= max).
PE=0 j.
Therefore ME =KE.
Since ME is constant.
So, PE = KE verified.
