This question was part of my worksheet and I amcompletelyclueless as to how i should even begin solving it:
1. Two books, initially on the floor, are picked up andplacedon a shelf 2.0 meters off the floor. One has a mass of 1.0 kgandthe other has a mass of 2.0 kg. The gravitational filedstrengthnear the surface of Earth is approximately 10 n/kg.
a. Calculate the gravitational forceactingon each book as it rests on the shelf. What factors determinethesize of this force?
b. calculate the change in eachbooksgravitational potential energy as a result of being picked upoffthe floor and placed on the shelf. what factors determine thesizeof this change?
c. what is the difference ingravitationalpotential between the floor and the shelf? whatfactors determinethe size of this difference?
d. how does gravitational potentialdifferfrom gravitational potential energy?
A 1.0 kg book initially at rest falls from a height of 1.5 mtothe floor.
A) Does the gravitational potential energy at the initialandfinal points depend upon the location of the origin ofthecoordinate system?
B) Does the change in gravitational potential energydependupon the location of the origin of the coordinatesystem?

When an 86.0 kg adult uses a spiral staircase to climb to thesecond floor of his house, his gravitational potential energyincreases by 1.70 x 10 to the 3 Joules. By how much does thepotential energy of a 24.0 kg child increase when the child climbsa normal staircase to the second floor?
