I'm not asking for ideas, just for resources so I can learn some basic particle physics.

Hi everyone! I am a high school student and I was wondering if anyone could provide some materials to help a high schooler study modern particle physics. I am interested in participating in the Beamline for Schools competition, which is where a team of high school students submits a proposal for...

I, too, remain unaware of said chat room.

Alright, that's what I expected. Thanks for the help!

Thanks! So why doesn't torque play a role here? Or is it just that the torque doesn't affect the linear acceleration?

Ah, I see, thanks! So both the magnitude and direction of the center-of-mass accelerations are all equal?

I think Fnet=ma can be applied here... Masses are the same, and the center-of-mass accelerations of B and C are the same as B and C reach the bottom at the same time. It follows that the net force on both are the same, and since normal force and force of gravity are the same on both objects...

Well, now that I think about it, none... however by intuition it seems like exerting force on the side of the block causes it to turn in a circular fashion...

Force of static friction on C is μsN, force of kinetic friction on B is μkN. Normal forces are the same because forces due to gravity are the same. However we don't know the coefficients of friction, so I don't see how I can show that these forces of friction are the same...

So the static friction would be nonzero, but after the ball starts rolling, it has zero kinetic friction, right? So would the static friction of object C equal the kinetic friction of object B, since they reach the bottom at the same instant? Or does the static friction have no effect on this?

Homework Statement Three identical rectangular blocks are at rest on a level, frictionless surface. Forces of equal magnitude that act in the same direction are exerted on each of the three blocks. Each force is exerted at a different point on the block (indicated by the symbol "x"), as shown...

What do you mean? Are you talking about static friction, too?

Hey, sorry to bother you, and I know this was a long time ago, but I am working on this problem too. Regarding your question-- the frictional force would be greater for object B than for object A, as it reaches the bottom first, right? And because object C is rolling without slipping, it would...

Yeah, just a typo. Thanks for all the help!

Oops never mind. I meant if torque decreases, angular acceleration decreases
