2A.4 Terminal Velocity Flashcards
1
Q
the viscous drag would vary with…
A
speed
2
Q
what is terminal velocity
A
the velocity of a falling object when the wight is equal to the sum of the upthrust and the drag
3
Q
what is strokes law =
A
6 x pi x r x coffient viscosity x v
4
Q
in simple situations the drag force is
A
directly proportional to the radius of a sphere and velocity
5
Q
what does the v term = to
A
v = 2r^2g(ps-pf)/9coffient of velocity
6
Q
terminal velocity is proportional to
A
the square root of the radius of a sphere, therefore the bigger the sphere is the faster it falls, furthermore, the radius is squared so it falls faster
