    Hi, new befuddled highschool physics student here!

    Seeking aid from this forum because I am drowning in questions for physics...I thought learning physics in high school would allow me to understand the mechanics of the world better...instead it's making me more confused. (Worried) I'm in your care! (Bigsmile)

    Roller Coaster Physics: From a dumb graduate student who forgot all his education

    Out of curiosity and not out of any desire to test this, would you be able to stay on a roller coaster without any restraints going around a loop? (e.g. if you came to a loop without a seatbelt, would you fall out and die)

    could a student survive

    While running a 70-kg student generates thermal energy at a rate of 1200 W. To maintain a constant body temperature of 370 C, this energy must be removed by perspiration or other mechanisms. If these mechanisms failed and the heat could not flow out of the student’s body, for what amount of time...

    Help an Australian Engineering Student Pass His Numerical Analysis I exam!

    Hey all, I've run into a bit of trouble regarding State vectors and expressing equivalent first order equations. We have a useless lecturer who spent all of five seconds on the topic yet it seems to be a frequent exam question. Judging by the point allocation to the question it's probably not...
