- What are some example's of hydraulic lifts?
- What does Pascal's Principle state?
- What is area measure by?
- a that the buoyant force that is acting on an object is equal to the weight of the water that is displaced
- b when a force applied to a confined fluid the change is pressure is equally transmitted through the fluid.
- c mass/volume
- d meters squared
- e fire truck, machines that raise cars
5 Multiple choice questions
- chimneys, planes (flying disks), and atomizers
- By increasing its density with water and overcoming the buoyant force by adding more weight and not changing the volume and therefore not displacing anymore water to increase the buoyant force.
- a force that acts in the opposite direction of gravity
5 True/False questions
How do chimneys take advantage of Bernoulli's principle? → the wind on top of the chimney creates a lower pressure at the top, on the bottom is a greater pressure which forces the smoke and heat to rise
How do planes (flying disks- same concept) take advantage of Bernoulli's principle? → the shape of their wings are curved on the top which creates a greater distance and air has to cover to match the speed of the bottom of the wing. Therefore, the fluid on the top of the wing moves faster and creates a lower pressure while the bottom of the wing has a greater pressure causing a lift. this lift make the wing rise and the airplane with it.
A submerged object displaces an amount of liquid.. → equal to the volume of what is submerged.
What is pressure? → The amount of force exerted on a surface
How could you measure pressure? → with a barometer
