MASS

Mass is a measure of how much matter is in an
object.

This gold bar is quite small but
has a mass of I kilogram (about

2.2 pounds), so it contains a
lot of matter.

Mass id commonly measured by how much

something weights. But weight is caused by
gravity, so your weight on the moon is less than

here on earth, while the mass stays the same.

Mass is measured in grams, kilograms, and
tonnes (metric) or ounces and pounds (US

units).
