NEWTONS LAW OF UNIVERSALGRAVITATION
NEWTONS LAW OF UNIVERSAL GRAVITATION
Newton’s law of universal gravitation – every object in the universe attracts
every other object in the universe with a force that is directly proportional to
the product of their masses and inversely proportional to the square of the
distance between their centres
The gravitational force of attraction between any two masses
The force depends on the masses of the earth and you, the force
weakens with distance
(m 1 x m2)
F=G always a force of attraction
r2
F = gravitational force of attraction
G = 6.7 x 10-11
m1 and m2 = masses of the objects
r = distance between their centres
The inverse square law = distance doubles, force quarters. Distance triples
force ninths
GRAVITATIONAL FIELD STRENGTH
Gravitational field strength – the gravitational force exerted on an object per
kg of the objects mass
g = 9.8m.s-2
This is a measure of the Earths gravitational field strength. The earths
gravitational field strength is 9.8N.kg-1 this means every kg of mass will
experience 9.8N of attractive force
