1
Q
Pressure
A
The ration of force to the area over which that force is distributed: Pressure = force/ area
2
Q

A
weight density X depth
3
Q
Buoyant force
A
The net upward force that a fluid exerts on an immersed object.
4
Q
Achimedes’ Principle
A
An immersed body is buoyed up by a force equal to the weight of the fluid it displaces.
5

A
The tendency of the surface of a liquid to contract in area and thus to behave like a stretched elastic membrane
7
