Fluids Forces

Front

What is a fluid?

Back

A fluid is a substance that can flow and take the shape of its container. This includes liquids and gases.

Front

What is pressure in the context of fluids?

Back

Pressure is the amount of force exerted on a given area, often measured in Pascals (Pa).

Front

What is buoyant force?

Back

Buoyant force is the upward force exerted by a fluid on a submerged object, which helps the object float.

Front

What does Archimedes' principle state?

Back

Archimedes' principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.

Front

What is Pascal's principle?

Back

Pascal's principle states that when pressure is applied to a confined fluid, the pressure change is transmitted equally in all directions throughout the fluid.

Front

How does air pressure change with elevation?

Back

Air pressure decreases as elevation increases.

Front

What is viscosity?

Back

Viscosity is a measure of a fluid's resistance to flow; thicker fluids have higher viscosity.

Front

What is Bernoulli's principle?

Back

Bernoulli's principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or potential energy.

Front

What is the relationship between fluid density and buoyancy?

Back

An object will float if it is less dense than the fluid it is in; it will sink if it is more dense.

Front

What is the formula for calculating pressure?

Back

Pressure = Force / Area.
