A) Prove the equality of potential, kinetic and elastic energy by substituting units into their standard formulae

Could anyone help or provide resourced to help.
I am doing an access to science course and I have never even done physics at GCSE level, nor have I even got a good grade or knowledge of maths ... lol

(Gravitational) Potential energy = mgh

Kinetic energy = 1/2 mv^2

Elastic (potential) energy = 1/2kx^2 = 1/2Fx = F^2/2k

Replace units and show they all have units of joule (kgm^2s^-2)
