Fluid Forces chapter 2 prentice hall explorers series

If you divide the force exerted on a surface by the total area of the surface, you will know

• density

• pressure

• lift

• buoyant force

If you know the weight of an object that floats, you know the

• object's density

• object's mass

• object's volume

• object's force

If you divide the mass of an object by its volume, you know the object's

• mass

• weight

• density

• pressure

The concept that increase in pressure on a confined fluid is transmitted equally to all parts of the fluid is known as

• Pascal's principle

• Bernoulli's principle

• Archimedes' principle

• Newton's third law

The concept that the pressure in a fluid decreases as the speed of the fluid increases is known as

• Pascal's principle

• Bernoulli's principle

• Archimedes' principle

• Newton's third law

Pressure is force per unit of mass.
