1. 5/22 Opener What are the forces acting upon the iceberg?

2. Forces What is weight? What is buoyancy?
The downward force of gravity acting on an object
What is buoyancy?
Buoyancy is the upward force that keeps objects afloat

3. What causes Buoyancy? Archimedes’ Principle:
An object is buoyed up by a force equal to the weight of the fluid displaced by the object.
Buoyancy = Volumeobject x densityfluid
B = (Vobject) x (Pfluid)

4. Types of Buoyancy
Positive Buoyancy: The object has a lesser density than water and floats.
Negative Buoyancy: The object has a greater density than water and sinks.
Neutral Buoyancy: The object has the same density of water and neither sinks nor floats.
