Chapter 3 Notecards

What is the formula for pressure? Force/Area

What are the units for pressure? (Not the guys name) N/M²

At higher elevations the air pressure is _________________ compared to the air pressure at lower elevations Lower

An object under water feels lighter than it does in air because of Buoyancy

Pressure spreading equally to all parts of a confined fluid is an example of __________ principle Pascal’s

If an object is dropped into a beaker full of fluid and sinks. What can you say about that objects density? The objects density is greater than the fluid

If fast moving air passes between two balloons, the balloons will…… Move together

The air moves more quickly against the curved top edge of aircraft wing compared to the bottom edge. This causes the plane to Rise (Increase Elevation)

Bubbles rise in soda because The bubbles are less dense than the soda

Pumps such as your heart work because of ____________principle Pascal’s

A device that increase force due to pressure is called a _______ device. Ex. Brakes Hydraulic

Mass per unit volume is the definition for this term Density

The faster that a fluid is moving past the object, the _________the pressure will be Less

The pressure exerted by the gas in the Earth’s atmosphere is called Air or Atmospheric Pressure

A fluid is a substance whose _________can easily change Shape

Water pressure _________ with depth increase

Buoyant force always works in this direction Upward

The weight of displaced fluid = the buoyant force of an object is _______________ principle Archimedes' principle
