How can we measure properties of matter?

-Gravity pulling down the matter of an object

-DOES change no matter where you are - no weight on the moon!

WEIGHT

-How much matter an object contains

-Does not change no matter where you are

​MASS

Mass: measure how heavy or light an object is

​

Volume: measure how much matter that object could hold

​

Length: measure how long an object is​
