Ck-12 Fluid Forces

Front

What does Archimedes' principle state about buoyancy?

Back

Archimedes' principle states that an object submerged in a fluid experiences an upward buoyant force equal to the weight of the fluid displaced by the object.

Front

How does fluid pressure behave in different directions?

Back

Fluid pressure is exerted in all directions, not just downward.

Front

Why does ice float on water?

Back

Ice floats on water because it is less dense than water.

Front

What is the relationship between pressure and fluid density?

Back

Denser fluids exert greater pressure than less dense fluids.

Front

What is the direction of fluid particle movement in relation to pressure?

Back

Particles of a fluid move from areas of higher pressure to areas of lower pressure.

Front

What is the definition of fluid density?

Back

Fluid density is the mass per unit volume of a fluid, typically expressed in kilograms per cubic meter (kg/m³).

Front

What is the significance of fluid pressure in engineering applications?

Back

Fluid pressure is crucial in engineering applications as it affects the design and functionality of systems like hydraulics, aerodynamics, and fluid transport.

Front

What factors affect the pressure exerted by a fluid?

Back

The pressure exerted by a fluid depends on its density, the depth of the fluid, and the gravitational force acting on it.

Front

How does temperature affect the density of fluids?

Back

As temperature increases, the density of most fluids decreases, causing them to expand.

What is Pascal's principle?

Back

Pascal's principle states that a change in pressure applied to an enclosed fluid is transmitted undiminished throughout the fluid.
