A 2 kilogram cat is resting on top of a bookshelf that is 1 meters high. What is the cat's gravitational potential energy relative to the floor?

Given:

Mass of the cat: 2 Kg

Height from the ground: 1 meter

Now we know that

Potential energy = mgh

Where m is the mass of the cat

g is the acceleration due to gravity m/s^2

h is the height from the ground in meters

Substituting the given values in the above formula we get

Potential energy = 2 x 9.8 x 1 = 19.6 J
