Chapter 4 Lesson 1 Pressure and Density of Fluids Daily Grade

What do we call the the amount of force per unit area applied to an object’s surface?

• fluid

• pressure

• buoyant

This is a measurement of the amount of matter, or 'stuff', in an object or substance.

• volume
• density
• mass
• length

When pressure is applied to a confined fluid, the increase in pressure is transmitted equally to all parts of the fluid. This fact is called________.

• Pascal's Principle
• Newton's Principle
• Archimedes' Principle
• Bernoulli's Principle

What is the formula for pressure?

• P=A/F

• P=FA

• P=F/A

The pressure resulting from a force of 50 N exerted over an area of 5 m² is

• 10 N
• 0.1 N
• 10 N/m2
• 0.1 Pa

Pressure decreases when the surface area over which it is applied .....

• pressure increases

• pressure decreases

• pressure stays the same

• pressure increases then decreases
