Mass and WeightMass and Weight

A common A common misconceptionmisconception throughout throughout the world of science is that weight the world of science is that weight and mass are the same thingand mass are the same thing

WeightWeight

WeightWeight: The measure of the : The measure of the

gravitational force exerted upongravitational force exerted upon

an object on Earthan object on Earth

We use a SCALE to measure weight

Weight a minute…Weight a minute…

Weight is varied on where the Weight is varied on where the object is in relation to the Earth (or object is in relation to the Earth (or any large body in the universe)any large body in the universe)

MassMass

MassMass: the amount of matter in : the amount of matter in a given objecta given object

We use a BALANCE to measure mass

Mass is…Mass is…

Always constant for an object no Always constant for an object no matter where the object is in the matter where the object is in the universeuniverse

Units?...we don’t need no Units?...we don’t need no stinkin’ units!!!stinkin’ units!!!

Every measurement has a common unit Every measurement has a common unit of measurement that accompanies itof measurement that accompanies it

Well, What Is Matter Then?Well, What Is Matter Then?

MatterMatter: anything that mass : anything that mass and takes up spaceand takes up space

Everything is made up of matter, Everything is made up of matter, therefore everything has…therefore everything has…

I can’t hear it…turn it up!!! I can’t hear it…turn it up!!! Turn what up????Turn what up????

VOLUME: the amount of space VOLUME: the amount of space an object takes upan object takes up

1. You can use the mathematical equation:

volume of cube= length x width x height

2. Use a graduated cylinder

3. See how much water it displaces by placing it in water

More units? More units?

Yes, more units…Yes, more units…

TemperatureTemperature: a specific degree : a specific degree of hotness or coldness of hotness or coldness

We measure this with the usage of a

thermometer, but what type of

thermometer????
