Mass is the amount of matter in an object and is measured using a balance with units of grams or kilograms. Weight is a measure of the force of gravity on an object and is measured using a spring scale with units of Newtons or kilograms. Unlike weight, mass stays the same no matter where an object is located in the universe, while weight can change depending on the gravitational pull of different locations.

1. What is
Mass?

2. Mass:
The amount of matter (or stuff) in
an object.
We use a balance with a fulcrum to
measure it.
The metric unit is grams or kilograms.

4. Weight
It’s a measure of gravity.
We use a spring scale to
The metric unit is the Newton
(g/m2
), though kilograms are
also used.
