100
ability to float
What is buoyancy
100
formula for density
What is mass/ volume
100

system that applies Pascal's Principle

What is a hydraulic system (example: brakes)

100
a push or a pull
What is a force
200
What happens to pressure if you increase area
What is pressure decreases
200
direction buoyancy acts
What is upward or opposite of gravity
200
how to label density
What is g/cm^3 or mass label by volume label
200

his principle states, when force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid

Who is Pascal

200
2 of 4 types of friction
What is sliding, static, rolling, and fluid
300
SI unit for pressure
What is pascal or 1 N/m ^2
300
increasing this allows more buoyant force to push up on you (why you turn on your back to float)
What is surface area
300
An objects density compared to the liquid if it sinks
What is more dense
300

force that opposes the motion of an object through a fluid

what is drag force

300
formula for speed
What is distance/ time
400
Direction that fluid pressure is exerted
What is every direction evenly
400
who's principle states that the buoyant force acting on a submerged object is equal to the weight of the fluid the object displaces
Who is Archimedes
400
why a helium balloon floats
What is less dense then the air around us
400

states that the pressure of a fluid decreases when the speed of that fluid decreases

What is Bernoulli's Principle

400
SI unit for force
What is newton (N)
500
When climbing a mountain, the elevation where there is the most pressure
What is sea level or bottom of mountain
500
If you dropped an object into a tub of water and it displaces 50 centiliters of water, what is its weight?
What is 50 grams
500
How a submarine is able to dive under water and come back up
What is changes densities- has tank full of air and then fills with water, and again pumps out to be filled with air
500

If the surface area between piston A and piston B piston is increase 9 times, what is the force exerted on piston B increased by

What is 9

500
Newton's 3rd law of motion
What is for every action, there is an opposite but equal reaction (actions come in pairs)
