Mass
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
Mass measures the amount of matter in an object, commonly determined by comparing it against a standard mass on a balance.
Show
Placing a rock on a balance against reference masses tells you its mass without gravity entering the comparison.
Watch for
A bathroom scale reading is often reported in mass units out of habit; the scale actually responds to gravitational force, not mass.
