Dark Tide - Physics concepts (L4 only)

force

A push or a pull

pressure (definition)

the amount of force exerted per unit area of a surface

viscosity

A liquid's resistance to flowing

newtonian fluid

constant viscosity, does not change with applied stress

nonnewtonian fluid

viscosity can change depending on the applied stress

density

mass/volume, kg/m³, g/cm³ = g/mL

velocity

the speed of an object in a particular direction

cylinder volume (equation)

V=πr²h, Volume = pi radius radius * height

weight (definition)

A measure of the force of gravity on an object

weight (equation)

weight = mass x gravity, w =mg

pressure (equation)

Pressure = Force/Area (P=F/A)

newton (definition)

SI unit of force, 1 N = (kilogram*meter)/second²

pascal (definition)

SI unit of pressure, 1 Pa = 1 Newton/1 meter²

total pressure

sum of all the pressures felt by an object, at the bottom of the pool you would feel the pressure of the water AND the pressure of earth's atmosphere

Liquid pressure (equation)

density gravity depth

flux meter

Measures the volume of a fluid going through a cross-sectional area per unit of time

mass flow rate

the amount of mass flowing through a cross-section per unit time (kg/s)

volume flow rate

the volume of a fluid flowing through a cross-section per unit time (m³/s)
