an airplane isn't a car, the wheels aren't driven. the propeller/jet will pull/push the plane regardless of what the wheels are doing, given they're not locked or something. brewnog got it right, think about it.

wow thanks, that is awesome. :smile: I really appreciate it! thanks!

wow thanks, that book looks awesome, and the kits too. this is just what I was looking for, thanks a lot!

Hey all, quick question here. I'm doing my first year of ee at college right now, and while some of the classes I'm taking (physics etc) are helping me very much to understand some of the topics, I'm getting extremely eager to practice some circuit design (my first circuit design class won't be...

thanks for the reply btw, I really appreciate it. I know it's a fact that currents and magnets create and feel forces from magnetic fields, while stationary electric charges do not. What I don't understand is what it is about a moving charge as opposed to a stationary one that makes this true...

Friction force = (coefficient of friction) * (normal force) F = ma all you need

that sounds suspiciously like a homework problem

anybody else want to give it a shot?

you lost me on the last sentence there.

ah okay, so basically I just don't have the right tools at the moment to understand why?

SWEET! I was hoping for something more along the lines of what's happening at the atomic level. My books provides a ton of equations, but no explanation whatsoever as to why they work.

Hello, I have a quick question. Why is it that a magnetic field has an effect on a current or moving charge, but not on a stationary charge?
