A substance that assumes the shape of a container is called
Fluid
Four examples of fluids
Air, oxygen, oil, water
What do people refer to above sea level
Altitude
Does air exert a force of more than 1000 N on top of your head
True
What keeps your body from being crushed by air pressure?
The pressure inside your body balences the pressure outside
If you squeeze a container filled with fluid does the pressure increase equally throughout the fluid
Yes
What happens when there is a change in pressure at any point in a fluid
The change in pressure is transmitted equally
The science of applying pascals principal is called
Hydraulics
what is exerted on the larger area of the output piston in a hydraulic lift system
Fluid pressure
What is Bernoulli principle
As the speed of fluid increases , the pressure within the fluid decreases
What is a spoiler
It creates a downward force that improves traction
What is buoyancy
The ability of a fluid to exert an upward force on an object within it
What direction does a buoyant force act?
Opposite of gravity
The greater the density of a fluid the grater is bout ant force?
Yes
What does bouyance cause in the weight of an object
Loss
