Question

What is the potential energy of a 3kg ball that is on the groundPotential Energy = Weight x HeightWeight = Potential Energy / HeightHeight = Potential Energy / WeightWeight = Mass x 10Mass = Weight / 10

Answer 1

The potential energy is given by

P=mgh

where

m is the mass.

g is the acceleration due to gravity

h is the height.

Here the ball is on the ground.

Thus, h=0

So,

P=3x9.8x0=0

Thus there is no potential energy
