The gravitational potential energy

Hi everyone,

On Thursday we learn some interesting facts about GPE that equation of PEG = -Gm1m2/R is always produces a negative value.As R increases,the masses get further apart,PEg increases by becoming less negative.As R increases to the point of approaching infinity R → infinity,the potential energy approaches zero,PEg → 0

The differences between

FGand EGPE

1. F inversely 1/R square E inversely 1/R

2. is a vector quantity is a scalar quantity

3. S.I unit measured in Newtons S.I unit measured in Joules
