Force and pressure are closely related but they are NOT the same thing (true or false).
What is False
100
The ability to float.
What is buoyancy.
100
When you push one part of a balloon, other parts of the balloon bulge out.
What is an example of Pascal's Principle
100
Fluid naturally flows from an area of higher pressure to an area of lower pressure.
What is fluid motion
100
Increasing pressure on a barometer is often a sign.
What is of fair weather.
200
What happens to pressure as the area over which the force is distributed?
What is increases.
200
A fluid exerts pressure on all surfaces of a submerged object. (True or false).
What is ture.
200
This multiplies force by applying the force to a small surface area.
What is a hydraulic systems
200
Explains how planes fly, why smoke rises out of chimney's, how atomizer works, and how a flying disks glides through the air.
What is applying Bernoulli's principle
200
Copper has a density of 4.44g/cm3. What is the volume of 2.78g of copper
What is .63cm3
300
This is equal to the force exerted on a surface divided by the total area over which the force is exerted.
What is pressure
300
States that the buoyant force acting on a submerged object is equal to the weight of the fluid the object displaces.
What is Archemedes' Principle
300
A car's brake system multiples the force of the driver's tap on the brake pedal (true or false).
What is true.
300
An upward force due to the different air pressure above and below an object.
What is a lift.
300
What is the density of mercury that has a mass of 39.6 g and a volume of 9.00cm3
What is D=4.40g/cm3
400
This is something that can easily flow, can change shapes (liquid or gas), and allows particles to move constantly in all directions.
What is fluid
400
Why a ship floats.
What is a ship floats as long as the buoyant force acting on it is equal to it's weight.
400
Brakes can be an example of this.
What is a hydraulic system.
400
The faster a fluid moves, the more pressure the fluid exerts (true or false).
What is false.
400
A force of 160 N is exerted on a surface with an area of 40m2. What is the pressure of that area?
What is 4Pa
500
Describe the difference between atmospheric pressure and elevation and water pressure and depth.
What is as elevation increases, atmospheric pressure decreases and water pressure increases as depth increases Go higher=less pressure Go deeper=more pressure
