I am looking for an explanation about a simple physics phenomen. When washing plates and ustensils, I would manipulate knives and, from times to times, would cut myself a bit. Does it matter if your hands are wet or dry and what does the water do on the surface of the skin that can influence...

Thanks for the explanations ! It made me think of more questions. Sorry it's more lengthy this time :-p If the Earth is attracted by the sun, why aren't we ? Or are we, having a mass lighter in the day at noon than during the night at midnight? And somewhat along Redfox's hairy vector, (...

I was wondering what kind of force is the force of gravity ? Is there a subcategory of that specific force ? (Got any internet documentation about it, too ? It would be nice.) I got another question: in the air, are there particle of metals (negligeable when studying the air's components)...

Anyone else has something to add ?

Right to the point: I am looking for a chainmail. However, I have no experience, I ain't used at working metal and don't want to buy it as it's pretty expensive (it takes more time than talent, I'd say) so I have decided to make it myself. I got information on how to fabric it but I really...

I'm looking for some wire that I can purchase in a nearby store. I want it mostly cheap, flexible (it's for fabrication), easy to take care of (doesn't oxidize) and if possible, light. I thank anybody that can help me the slightest since I've been looking a while through internet without...

something is wrong with your calculation I think T is confused with τ and R^2*-a/r is derived into a*(R/r)^2 otherwise the answer makes sense either way (r² or r) lastly, you're corect sir Mason, I did translate my cm in mm AND add the mm sign therefore doing the process twice.

What would be the acceleration of a yo-yo if these are my datas: m= 10.456g r(small) = 0.7mm R= 1.9mm Now on I've had accelerations varying from 0.006m/s² to 930m/s² -yeah right... Worked on that prrety all of the time today and all I got left is a few so that I'm really in a hurry...
