Notes - rearranging equations
Goal is to get an equation into the format of (wanted variable) = ____________
Use opposite functions to move variables around in an equation
Will need to do this with equations from now on
Notes - mass and weight
Mass
The measure of the amount of matter that makes up something
related to the number of atoms in an object
measured in kg
measured using a balance
Does not depend on gravity (or, therefore, location)
Weight
The measure of the force from gravity on an object
Depends on the size of the object and the amount of gravity
Measured in N (since it is a force)
Can be changed by going to a place with more or less gravity (changing altitude on Earth, going to the moon or another planet)
Mass and Weight Lab (due Tuesday)
