# Newtonian Gravitation

!Sir Isaac
Newton All
objects on Earth are pulled downward, towards the ground. This
phenomenon is called **gravity**. Every object falls just as fast as any
other object (unless the air slows it down like a feather, or pushes it
up like a balloon), as first shown by
Galileo. In 1687 Isaac
Newton stated that gravity
is not restricted to the Earth, but instead, there is gravity everywhere
in the universe. Newton explained that planets, moons, and comets move
in orbits because of the effect of gravity.
