Oil & Water – Slow Motion

Physical Properties

Physical PropertiesEverything in the universe is either matter or energy

Matter – anything made of atoms (has mass and volume)

Mass – measure of atoms an object contains

Too tough to count atoms, so we use grams, kilograms

Volume – amount of space an object occupies (3D)

Regular shapes like a cube have equations: L x W x H

Liquids are measured in milliliters or liters

𝐷𝑒𝑛𝑠𝑖𝑡𝑦 =𝑀𝑎𝑠𝑠

𝑉𝑜𝑙𝑢𝑚𝑒

Density is the compactness of an

object; how much stuff packed into

how much space
