Question

Which of these is not a conservative force and does not have a form of potential energy connected with it?

Answer 1

gravity

electric attraction and repulsion

friction

magnetic attraction and repulsion

Answer 2

Do you know what conservative force is?

Answer 3

Head up: Magnetic + Friction are not conservative.
Gravity is. Not sure about electric I think its not.

Answer 4

heads*

Answer 5

@OneOwOne :O
do you even know what conservative force is? :O

Answer 6

thanks i thought it was gravity just needed confirmation

Answer 7

waht?! :O..

Answer 8

I don't think you have understood it ... clearly OneowONe hasn't :-/

Answer 9

what then?

Answer 10

do you know what a conservative force is?

Answer 11

no i don't

Answer 12

then how do you possibly intend to answer that question?! :-/.. don't you think you need to learn about it?

Answer 13

are you trying to help or give me a dictionary ?

Answer 14

I have the answer already

Answer 15

rath do you have an answer?

Answer 16

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

Answer 17

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

Answer 18

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

Answer 19

aww.. hope physics will treat you better in the future. Good luck :)

Answer 20

its not your fault.. you just had a bad teacher :D

Answer 21

Answer 22

@Mashy I'm not sure what it is... Reviewing it as we speak!
But I know that magnetic interaction is not conservative...

Answer 23

no no.. i was wrong.. i thought magnetic interaction was conservative.. btu yes you are right.. its not :)
