Sweet, thanks for the info. This should make for a harder to design CSS periodic table hehe. I was hoping i was going to be able to just group them into the other groups... oh well.
I'm designing an online periodic table of the elements and I have a question about the lanthanide and actinide families. I notice that all periodic tables put them below the main table, aligned with groups 4-18. Does this mean that they fit into those groups? Or is it just placed like that to...
Hey, thanks for that explanation Gokul43201. I asked my dad a few days ago and he told me to look up magnetic forces and to take note that it is a conservative force like you say. I did some reading and I was arriving towards the conclusion you give, but you make it very clear now.
My...
My understanding is that there is no gravitational force in the abscence of another mass to interact with. F = Gm1m2/r^2 (Unless there are two masses, then this force is 0). In other words, gravitational force is not a property a mass exhibits constantly, but rather when it is interacting with...
That's sort of what I was thinking. If the magnet is strong enough to pull it up the ramp, then why wouldn't it be strong enough to keep it from falling.
I wasn't sure where to post my question but it seems like it would belong here. I was hoping for an anti-physics category or something hehe. I apologize in advance if I was wrong. Anyway, I've been reading about perpetual motion machines and I understand the physics behind them and why they are...
Thanks for that linkk Jeff, it was pretty interesting. However I'm still curious about this rotating scenario. What kind of forces would your body experience in such a rotating motion. Wouldn't there be a big acceleration in a short period of time as your organs go from pressing against the...
Hey guys, this is my first post here. I found the forum because I've been thinking about a scenario and I can't figure out what would happen, and well what better place to ask about this than a place called "physicsforum.com" :D.
Ok so here it is: Imagine you are strapped to a seat inside of...
