GPE=mgh
where: m=mass of the object
g=9.8m/s^2 (constant)
h=height above the ground

Given:
m=1.0g
m=0.001kg (converted)
g=9.8m/s^2
h(book-table)=0.5m
h(table-floor)=1.0m
h(book-floor)=1.5m

Find: GPE

Solution:
GPE=mgh
GPE=(0.001kg)(9.8m/s^2)(1.5m)
GPE=0.0147kg•m^2/s^2
or
GPE=0.0147J

Final Answer: 0.0147J
