Which object has the most gravitational potential energy?

a. a 30 kg suitcase at a height of 1.5 m b. a 20 kg suitcase at a height of 2 m c. a 30 kg suitcase at a height of 2 m d. a 20 kg suitcase at a height of 1.5 m.

C.A 30 kg suitcase at a height of 2 m 

Explanation:

The gravitational potential energy (GPE) of an object is given by:

where

m is the mass

g is the gravitational acceleration

h is the heigth above the ground

We can use the formula to calculate the GPE of each object:

A.A 30 kg suitcase at a height of 1.5 m

B.A 20 kg suitcase at a height of 2 m

C.A 30 kg suitcase at a height of 2 m 

D.A 20 kg suitcase at a height of 1.5 m.

So, we see that the object which has the most GPE is C.
