Unformatted text preview: Vector sum=net force on object (must equal 0) Diffusion;twice as thick=4xlonger, 3Xas thick=9xlonger Circumference;double R=2C triple R=3C Surface area;double R=4SA triple R=9SA Volume;double R=8V triple R=27V No drag force when you first let go the particle from rest (v= a=v doesnt change as much terminal velocity) As speed picks up, drag force=a and velocity doesnt increase as much viscosity, mass=drag force The size of the buoyant force=weight off the fluid displaced by object Viscosity determines drift time...
