gravity electric attraction and repulsion friction magnetic attraction and repulsion
Do you know what conservative force is?
Head up: Magnetic + Friction are not conservative. Gravity is. Not sure about electric I think its not.
@OneOwOne :O do you even know what conservative force is? :O
thanks i thought it was gravity just needed confirmation
I don't think you have understood it ... clearly OneowONe hasn't :-/
do you know what a conservative force is?
no i don't
then how do you possibly intend to answer that question?! :-/.. don't you think you need to learn about it?
are you trying to help or give me a dictionary ?
I have the answer already
rath do you have an answer?
yea.. friction is the answer.. but conservative force is a beautiful concept.. so i thought you might be interested in learning .. even i didn't know magnetic force was not conservative :D
yep. Magnetic force is not conservative either. A brilliant lecture supplement by MIT ocw illustrates this beautifully: http://ocw.mit.edu/courses/physics/8-02-electricity-and-magnetism-spring-2002/lecture-notes/lecsup41.pdf
well i hate physics sooo i really don't care for it as much...well i care about getting a good grade but i still hate it
aww.. hope physics will treat you better in the future. Good luck :)
its not your fault.. you just had a bad teacher :D
@Mashy I'm not sure what it is... Reviewing it as we speak! But I know that magnetic interaction is not conservative...
no no.. i was wrong.. i thought magnetic interaction was conservative.. btu yes you are right.. its not :)
