General Science - Fluid Principles, Light, and Sound

Flashcards covering General Science topics including Pascal's principle, hydraulic systems, fluid principles, Archimedes principle, buoyancy, communication, and navigation based on lecture notes.

pascal's principle

when pressure is applied to a confired fluid, the pressure transmitted equally in all directions.

hydraulic system

a madiène uses liquid to transfer force from are point to another

Incompressibility of liquids

the energy is transfered without any loss in efficiency.

Pascal's principle (Fluid Principle)

law that when pressure is applied it is transmitted equally.

Pascal's principle key idea

this principle does not create extra pressure or energy, it allows Save pressure act over a larger area producing a larger / greater output Paris.

archimedes principle

an object immersed in fluid expiriences an upwards buoyant force equal to the weight of the displaced fluid.

benoyancy

the upward free exexted by a fluid on an object immersed in it.

Weight (downward)

the force pulling the object done.

Bevoyant force (upward)

the Parce pushing the object up.

Formula for Buoyant Force

$$F_B = P \times g \times V$$

Buoyancy key idea

every object placed in water expiriences buoyancy even objects that even forty sink, it depends on the amount of Muid displaced by the object.

Communication

the process of sending and recieving information.

Navigation

the process of determining your location and finding the best route.
