Universal Law of Gravitation Worksheet
Newton's Universal Law of Gravitation (first stated by Newton): any two masses
m¡ and m, exert an attractive gravitational force on each other according to
m, m,
F = G
r2
m,
This applies to all masses, not just big ones.
G = universal constant of gravitation = 6.67 · 10-" N m² / kg² (G is very
small, so it is very difficult to measure!) Don't confuse G with g: "Big G" and
"little g" are totally different things.
Practice problems:
1. Consider a space shuttle which has a mass of about 1.0 x 10 kg and circles
the Earth at an altitude of about 200.0 km. Calculate the force of gravity that
the space shuttle experiences. (for the mass of the earth refer to the reference
table page 1)

whose centers of mass are separated by 1000 m?
