gravity: a non-contact force that occurs between all objects that have mass
Mass
mass: amount of matter in an object
Weight
weight: is the gravitational force exerted on an object.
Scales measure weight.
You weigh 10% less orbiting the earth
100 lbs 90 lbs
Your mass does not change.
Weight is relative
mass ≠ weight
