Consider body of mass is raised to a height 'h' above the ground level, the force acting on the body is the gravitational of the earth and equal to mg. This force acts in the vertically downwarddirection.To lift the body above the surface of tge earth, we will have to do work against this force of gravity. Let Work= force×displacement W = m×g×h W=mgh This work done on the body is actually the increase in potential energy of tge body. Hence work done is equal to potential energy. PE = mgh. read less

What produces more severe burns, boiling water or steam?
Steam will produce more severe burns than boiling water because steam has more heat energy than water due to its latent heat of vaporisation.

Why when a ball dropped from a height, its speed continuously increased?
the potential energy gets converted into kinetic energy so obviously yes. as velocity is the only variable , as the height decreases, there should be a corresponding increase in the velocity. (potential energy = mgh, kinetic energy = 1/2 mvxv
