Density & Graphing

Density

- The density of an object is it's mass divided by it's volume.

formula:

d=m/v

And is usually expressed in kg/L, kg/m cubed, or g/m cubed

Example

- Determine the density of a statue that has a mass of 135kg and a  volume of 65L

d= m/v

d= 135 kg/ 65L = 2.1 kg/L

Graphing


- All graphs must contain 5 important things:

1. Labelled axes
2. Appropriate scale
3. Title
4. Data points
5. Line of best fit

- There are 3 important things you can do with a graph:

1. Read the graph
2. Find the slope
3. Calculate the area

Archimedes Density and Dispalcement theory

Legend says that Archimedes discovered the principle of displacement while stepping into a full bath. He realized that the water that ran over equaled in volume the submerged part of his body. Through further experiments, he deduced the above mentioned Archimedes' principle.
