hey, i was looking for information on friction coefficient of marble on plastic and iron on plastic. if you know these values i'll be very glad! thanks in advance

That's my question exactly, if we consider an ideal case, what would make the current know that on the one side of a certain junction lies a resistor and on the other is the rest of the ideal wire bypassing the resistor?

Care to elaborate?

Let's say we have a circuit, and in that circuit there's a resistor, and there's a wire that goes around it so that the current can flow freely without getting to the resistor. my question is this: how does the current "knows" to flow towards the around the resistor? how does it know not to get...

How is it that momentum is being preserved in a non elastic collision? for example let's say that two balls are colliding head-on, not elastically and heat is produced, does that not reduce the momentum of the system?

how is the maximum force defined? when the object shatters? if so I'd assume the molecular bonds of that particular matter determine the maximum force wouldn't it? - because i guess you're talking of a situation when the wall or paper is stationary due to something holding it. and if it is so...

Thanks! so does that mean that the paper in your example has a force of 5N applied on it by my fist? or it has 10N but only capable of returning 5N? does the mass determine the resistance capability?

So there's something I'm missing when I think of Newton's 3rd law of motion. If all forces between two objects exist in equal magnitude and opposite direction, how is it that, for example, when I'm driving my car, the car "runs through" all the air molecules, and they seemingly don't exert the...

hahahahaha thanks for the lucid answers though!

Having an equal F in both cases, wouldn't plugging a greater mass in the equation results in a higher acceleration for the lighter body (because the denominator is greater)?

So, this may be a really stupid question, and I strongly feel as though I'm missing something here. How can it be that objects of different masses have the exact same acceleration when mass is in fact resistance to acceleration? And then, if in (a vaccum) I throw upwards M and m ( a bigger and a...
