• Matter – anything that has mass
• Mass - quantity of matter contained in an object
• Weight – the force of attraction between matter and earth
Person… on Moon… on Earth…
Mass same same
Weight 1/6 x W lbs. W lbs.
Gravity 1/6 G G
MATTER
– anything that has volume
• Volume – amount of space occupied by an object
