Do Now #6 - Archimedes Principle

Do Now# 6 - Why do you think an object sinks or floats in water? 

In class the other day we should have come to the realization that
1 cm cubed is  = 1mL. 
This is a 1:1 relationship. 
Therefore 100cm cubed is = 100 mL


Honors: What is one meter cubed = ?_____Liters




The reason is this.....a meter cubed is =
100 cm x 100 cm x 100 cm = 1,000,000 cm cubed or 1,000,000 mL
using the King Henry  Died by drinking chocolate milk you realize
that is = to 1000 L


Definition of DISPLACEMENT

1

: the act or process of displacing : the state of being displaced

2

:the difference between the initial position of something (as a body or geometric figure) and any later position.

Buoyant Force

The buoyant force is equal to the weight of the fluid displaced.  

When an object weighs less than the total volume of fluid it can displace it will submerge until the point that the buoyant force is equal to the mass of the object.  If you were to add more mass to the object it would sink more until reaching equilibrium with its buoyant force.

Archimedes Principle:
Science historians generally agree that the idea for his principle occurred to Archimedes as he entered a bath pool. As he waded into deeper water, the force on his feet became less.





Archimedes' Principle is that an object totally or partially immersed in a fluid (liquid or gas) is buoyed (lifted) up by a force equal to the weight of the fluid that is displaced.
