What is the formula for kinetic energy, potential energy and mechanical energy??

i) Kinetic energy = 1/2mv^2

m=mass , v = velocity.

ii) Potential energy = mgh

m=mass, g=acceleration due to gravity, h=height

iii) Mechanical energy = Potential energy(mgh) + Kinetic Energy(1/2mv^2)

      Mechanical energy = mgh+1/2mv^2
