Hey Guys a lot of people were asking me how to prove that centripetal acceleration is v squared over r. Well, i know quite a few people here might not know calculus, not that the calculus to prove it is very hard, but i prepared something for you guys. Its a beautiful proof which i like much more than any calculus proof. Its slightly amateurish because i've never really done this before. Hope it helps though, i think you can find the proof on wikipedia anyways. You can ask me if you guys need anything else.
This was published by Brownstein (AmJPhys 62(10), p. 946, October 1994). It was also in the PSSC materials.
Thanks. Heh, i didn't know about the publications ><. Thanks, and sorry for not crediting before this.
