Fluid and Pressure

What do we call the the amount of force exerted on a certain area?

• 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 SI unit use for hydraulic pressure?

• Kg/m³

• Pa

• Litre

• Kilometer

What is the formula for pressure?

• P=A/F

• P=FA

• P=F/A

To calculate pressure you need to know ...

• Force & Volume

• Density & Volume

• Power & Area

• Force & Area

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

A person wearing boots and a person wearing stilleto heels stand on a wooden floor. They both have the same weight. Which person exerts a greater pressure on the floor?

• boots because they have a larger surface area

• stiletto heels because they have a larger surface area

• boots because they have a smaller surface area

• stiletto heels boots because they have a smaller surface area

In what direction(s) does air exert pressure?

• everywhere
• no where
• there is no pressure
• downward

When force increases...

• pressure increases

• pressure decreases

• pressure stays the same

• pressure increases then decreases
