exactly is Mass?
You've probably heard of weight, right? Mass is
related to weight, but they are not the same.
is the measure of the quantity (amount) of matter that a body contains.
Weight is related
to gravity (an attractive force between two bodies).
Weight is equal to the product of the object's mass and the acceleration
of gravity. The larger the mass of the planet you're
on, the more
you will weigh.
So gravity must be
present for an object to have weight, but an object
has mass in both the presence and absence of gravity.
As you can see, weight is a little more complicated
than mass. It has to do with gravity, as well as mass.
Mass is simply a measure of the amount of matter.

If one bowling ball
was here on earth, and another bowling ball was floating
weightless in space, which one would have more
