Behavior of Fluids
Ch. 4 Sec. 3
When the speed of a fluid increases, the pressure exerted by the fluid decreases.
Buoyant force on an object is equal to the weight of the fluid displaced by the object.
When a force is applied to a confined fluid, an increase in pressure is transmitted equally to all parts of the fluid
F / A
An object will _______ in a fluid that is denser than the object
an upward force on an object immersed in a fluid.
measure of force
measured in square meters
M / V or mass / volume
pressure (x) area
the force exerted on a surface divided by the total area over which te force is exerted.
If force increases over an area, the pressure _________.
Air presses down on Earth with force.
As ______ increases, air pressure decreases.
Decreasing volume ______ pressure.
Increasing temperature ______ pressure.
_______ volume decreases pressure.
Decreasing temperature ______ pressure.
An object will ______ in a fluid that is less dense that the object.
