calculate the potential energy of a rock with a mass of 55 kg while sitting on a cliff that is 27 m high

Answer :

PE = mgh.

PE = Potential energy
M = mass
G = gravity
H = height

Now plug in the numbers. 

PE = 55 * 9.8 m/s^2 * 27
PE = 539 * 27 
PE = 14553 

Answer: Potential energy is 14,553 Joules
