3.00 g/cm^3
You have a slice of pizza. You take a few bites of the slice of pizza. Did the density of the pizza change?
No! The mass changed because you ate it, and the volume changed because you ate it, but that keeps the density the same.
What is the SI unit of for volume?
m^3
measures the amount of gravitational force acting on an object
Weight
A floating object is put into a liquid, and you watch the water level rise because of this. This rise in water level is known as_________ .

A pencil is floating in liquid A. Another pencil (of the same volume and mass) has sunk in liquid B. Use the terms density to make a comparison between liquid B and A.
Liquid B must be less dense than liquid A.
What is the formula in finding the density of an object?
density = mass/volume
