no need to brag about A*.....they proove nothing........i know many students who just put in 2 weeks before the exam and come out with straight A* in O and A levels.........but when u ask them a conceptual question...THEY FREAK OUT!!!!!!!!!!!any how i accept my mistake about the power out put as i myself saw that question in mcq today, how ever since ive seen n many places on net that power out put includes all forms of converted energy............(mainly in motors and engines) im convinced that both should be credited...its happened in past papers where there are two alternatives..just gotta make sense

hey bro..............what would be explanation of this calc?
hope u did M1, in M1 we say that power output of engine of a car is say 24000W, the resistive force is 500N and velocity is 10ms-1. so then in the quation we equate power output to (ma+r)(v)....right.....see we included the resistive force so useful work done is actualy less then power output..............oesnt that contradict the whole new conclusions which are apparently being drawn

U should remember we only use forward force.. P=Fv :p we do not include the resistive force here. And i guess u'll see now that i am right :D

It's still a mystery.But according to me your judgements or so called logics will prove fruitless in the end.No offence intended. It's meteoric thoughts that are satisfying you.:p

oh yar we ALWAYS include to resistive force when total output power is given, however only when we have excluded the out put force it is P=Fv...............

Well yes sweetheart. By your level of intellect I think you're still stuck in the "glory days" of your O levels. The main reason might be that your school must've treated you like a royalty for getting such average scores. So I don't blame you. It's not your fault 'big' guy.

You're right. He started bragging about it. Show offs like him have to be shown there place. I gave him explanations with proofs but his "insect" mind isn't comprehending his errors. And thankyou for accepting the mistake. Yes, I believe that both answers should be credited. InshAllah they will be.

At least my school taught me that the independant variable goes to the x axis and the dependant on the y axis :rolleyes:
