density equation?
mass/volume
what is the pressure equation?
force/area
what is force measured in?
newtons
what is area measured in?
m^2 or cm^2
what is the Bernoulli’s principle?
when the speed of a moving fluid increases, the pressure within it decreases
what was our experiment for bernoulli’s principle?
we blew over a piece of paper and it started wiggling up and down
what is the pascal’s principle?
when pressure is applied to a confined fluid, that pressure is exerted equally on all parts of the fluid
what is a buoyant force?
upward force in a liquid (contributory to gravity)
what is displacement?
the amount of fluid moved by a submerged or partially submerged object
what does the volume of liquid displaced equal?
the volume of submerged portion of the object
what is archimedes’ principle?
the buoyant force acting on a submerged or partially submerged object is equal to the weight of the fluid displaced by it
