generally it is given as proportional to v or v^2--the quadratic relationship is usually for larger objects. Most introductory material on diff eq use v. thanks
good point, I had assumed k to be unit-less, but its units are kg/sec (http://oregonstate.edu/instruct/mth252h/Bogley/w02/resist.html)
so F=kv would have the same dimension as F=ma. thanks!
Hi. Consider the basic eq for a falling body with air resistance
dv/dt=g-kv/m
I don't understand air resistance as a force, since it seems irreconcilable to the force equation F=ma. How is a force a function of velocity? I am also not sure how this equation makes sense in terms of...
