Pascal's Principle

Which statement correctly describes pressure?

• The applied force that acts on an object

• Force per unit area

• Force times surface area

• The area to which a force is applied

The amount of force pushing on an area is the definition of..

• Viscosity

• Pressure

• Fluid

• Barometer

Which of the following best suit the statement below?

Pressure applied to an enclosed fluid is transmitted uniformly to every point in the fluid and to the walls of the container.

• Bernoulli’s principle

• Archimedes principle

• Pascal’s principle

• Newton’s law

Pressure decreases when the surface area over which a force is applied increases

• True

• False

Hydraulics use liquids as a force to do work.

• True

• False

What is the equation for pressure?

• Pressure = Force / Surface area

• Pressure = Force + Surface area

• Pressure = Force x Surface area

• I have a 6 foot squirrel named Antney

Fluids can be...

• Solids

• Liquids

• Liquids or gases

• Gases

Assertion (A): Pressure is equal in all directions at a point in an ideal fluid flow

Reason (R): Pascal's Law is valid for all fluids.

• A is true, R is true and it explains A.

• A is true, R is true, but it does not explain A.

• A is true, R is false.

• A is false, R is true.
