Fluid Pressure

Front

What is fluid pressure?

Back

Fluid pressure is the force exerted by a fluid per unit area on an object or surface. It acts in all directions and increases with depth.

Front

How does fluid pressure behave in a closed container?

Back

Fluid pressure in a closed container exerts force everywhere inside the container, not just on the bottom or sides.

Front

What is Pascal's Law?

Back

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

Front

What is buoyant force?

Back

Buoyant force is the upward force exerted by a fluid on an object that is submerged or floating in it.

Front

What determines whether an object floats or sinks in a fluid?

Back

An object floats if the buoyant force is equal to its weight; it sinks if the weight is greater than the buoyant force.

Front

What is the relationship between weight and buoyant force?

Back

Weight and buoyant force work in opposite directions; the balance between them determines if an object floats.

Front

What is Archimedes' Principle?

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 causes fluids to exert pressure?

Back

Fluids exert pressure because their particles are constantly moving and colliding with surfaces.

Front

What is Bernoulli's Principle?

Back

Bernoulli's Principle states that as the speed of a fluid increases, its pressure decreases.

Front

How does depth affect fluid pressure?

Back

Fluid pressure increases with depth due to the weight of the fluid above exerting force.
