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

Helium atom has an atomic mass of 4u and two protons in its nucleus. How many neutrons does it have?
Mass number of Helium = 4 Number of protons = 2 Number of neutrons(n) = Number of Mass(A) — Number of proton (P) = 4 – 2 = 2 Thus, No. of neutrons = 2

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
