Density Flashcards
Density equation
Density = mass / volume
Density units
Kg/m³
What is density if volume of water is 0.5m³ has a mass of 500kg?
500 / 0.5 = 1000kg/m³
What is a veneer caliper
A tool to measure
How to use a vernier caliper
Use the main scale and the first and second lines that mark up perfectly give you the length
How to measure density of irregular object
Measure mass using top balance and volume with a displacement can
How to use a displacement can
Fill it up to the brim and drop the object in and the amount of water displaced is the objects volume
Terminal velocity of a falling sphere
Weight = upthrust + drag

Upthrust equation
U = P(f)Vg
Upthrust = Density of fluid x volume in fluid x gravity
Viscosity equation if W = U + fd
n = 2r²g(p of solid-p of fluid) / 9v
Viscosity equation if W + fd = U
n = 2r²g(p of fluid-p of solid) / 9v
Terminal velocity of rising sphere
Weight + drag = upthrust
