What is the simple equation for Drag on a slow moving object?

I've looked some equations up on google- but they aren't what I'm looking for.


My teacher told me drag is just the velocity squared.... is he right?What is the simple equation for Drag on a slow moving object?
Drag is a mixture of friction forces due to air resistance and friction in the moving parts (if any) and the surface the object is moving over. V squared is rubbish. mv^2 is momentum that must be overcome to start the object moving, then the other forces kick in.What is the simple equation for Drag on a slow moving object?
Drag is viscous force and is equals to





F=kv^2,where v=velocity
Drag force = (1/2)CpAv.v


where C=drag co-efficient


p=density of air


A=surface area of object


v=velocity of the object


Your teacher is right.
Alan M what the hell.. momentum is mv not mv^2, are you thinking of kinetic energy -


1/2 mv^2
