Density
Measured in
g/cm3
density of common substances
water
about 1 g/cm3
vegetable oil
about 0.93 g/cm3
mercury
about 13.534 g/cm3
steel
about 8.05 g/cm3
calculated using formula
Density=Mass divided by volume
Volume is
The amount of space an object takes up
measured using an overflow can for large irregular objects
calculated for regular shapes by multiplying height x width x breath.
measured using a small graduated cylinder for small irregular shaped objects
Measured in centimeter cubed (cm3) or metre cubed (m3)
Mass
The amount of matter in an object
Does not have direction
Measured by using a balance
The mass of an object always remains the same
Measured in grams (g) or kilogram(kg)
manipulated to
defined as
The density is a measure of the mass of a substance per unit volume.

Floatation
described as
the action of floating in a liquid or gas
an object floats if
It is less dense than the liquid it is placed in.
important in
Ship Building
a ship will float if
Its total density is less than the same volume of water
Archimedes Principle
