Question

A book weighs 0.5 kilograms on a book shelf that is 2 meters above the ground. What is the potential energy of the book relative to the ground? (HINT: you may use 10 N/kg as the value for gravity)

Answer 1

Using the GPE=MGH, M=0.5 kg, G=9.8m/s H= 2 m multiply those all together and we will have 9.8 J (joules)
