I'm writing a set of notes for my high school
physics students on
nuclear phyiscs, and I want to show them some particle tracks
after a collision in a particle accelerator. How can I get some of
these images that I can paste into a MS Word document and print up for
my students. I've searched the internet extensively and have not found
any images that will work. Can you help me?
Drag force is often a complex function of velocity and other
parameters. More specifically, it is related -- in a non-linear way -- to
a parameter known as the Reynolds number. This parameter lumps velocity,
viscosity, density and size into a single mathematical entity.
The precise nature of the relationship between drag force and Reynolds
number depends on such factors as the shape and surface roughness of the
projectile. These relationships are often established empirically, and one
refers to them for numerical calculation. Analytical solutions are often
May I refer you to an introductory text book on fluid mechanics where you
will find in-depth coverage of the subject.
