mass and weight.◦Use page 185
To Do List:OpenerNotes: Mass vs. WeightMass vs. Weight Venn DiagramHomework: Finish Worksheet
What do you need to know?Be able to define mass and
weight.Be able to explain the difference
between mass and weight.Be able to discuss the effect
gravity has on mass and weight.
Mass vs. Weight
Key VocabularyMassWeight
What is mass?Mass - is the amount of matter in
an object.◦Matter = something that has mass
and takes up space.◦Measured using a triple-beam
balance
What is weight?Weight – measure of the
gravitational force exerted on an object.◦Changes with location◦Weight = Mass X Gravity◦Measured using a spring scale
Differences between Mass and Weight
MassMass is a
measure of the amount of matter in an object.
Mass is always constant no matter where the object is located in the universe.
WeightWeight is a
measure of the gravitational force on an object.
Weight varies depending on where the object is in relation to the Earth (or any large body in the universe)
Compare/Contrast
What did you learn?Mass is the measure of the
amount of matter in an object.Mass is constantWeight is the measure of the
gravitational force exerted on object.
Weight can change depending on location, therefore it is not constant.
