What is mass
Mass is a measure of the amount of matter that makes up an object.

Matter
Weight
Weight is a measure of the gravitational force exerted on an object
We use ____ to measure mass
Balance
We use _____ to measure weight
Spring scale
Inertia
Inertia is the tendency of an object to resist a change in motion
Physical property
A physical property of matter can be observed or measured without changing the matter’s identity
Physical properties- a partial list
Color Volume Mass Shape Hardness Texture
Chemical properties
Chemical properties describe matter based on its ability to change into new matter that has different properties
Physical change
When a physical change happens, it affects one or more of the physical properties of a substance, but it doesn’t change the identity of the substance
Ability to born
Flammability and combust ability
Characteristic properties
Are useful in identifying a substance are called characteristic properties
Chemical changes
When matter undergoes a chemical change, a new substance is formed
