fluid
A fluid is any substance that can flow and take the shape of its container.
volume stays the same in
any container
gases are

pressure
is the amount of force per unit area applied to an object’s surface.
What do all fluids apply to the objects they come into contact with?
Pressure
What is pressure applied on any object by a fluid related to?
The weight of the fluid.
What is the equation for pressure?
pressure = force times area
force
push or pull on a object.
What is the unit of measurement for pressure? How do you abbreviate it?
Pascal. Pa
According to this paragraph, how does a fluid apply pressure?
It applies it to perpendicular sides.
which direction does the water apply pressure to the object in the water?
Perpendicular sides of the object.
How does pressure change as surface area changes
When the force applied over a small area pressure is greater the when the same force is applied to a larger area.
atmospheric pressure
the ratio of the weight of all the air above you to your surface area.
What does kPa stand for? What does that mean
Kilo pascal they rae way bigger than a normal pascal
