2 magnets...potential or kinetic?
« on: May 14, 2004, 11:15:36 AM »
hey guys, I'm having an argument with my friend and I need some input.  Here's the question:  if you have 2 magnets and you're holding them apart, is that kinetic or potential energy.

Kinetic Energy is the energy associated with motion.  An object that is completely still in all aspects does not have Kinetic Energy.  (Well, Quantum Physics can argue that in all shapes and forms).  Potential Energy is the energy which can be generated based upon the position of something, or a possible reaction.  So if you're holding two magnets apart, the energy involved is potential energy since if you let them go, their attraction for each other will put them in motion, thus releasing that potential energy in the form of kinetic energy.  Now it's been a while since I've taken a physics course, so if other members here would like to correct me go right ahead.   ;D

Thanx jdurg!  So your answer is Potential?  Anyone else care to take a stab at it?   ;D

My vote is with Jdurg.

Most Common Suggestions I Make on the Forums.
1. Start by writing a balanced chemical equation.
2. Don't confuse thermodynamic stability with chemical reactivity.
3. Forum Supports LaTex

potential.
once you let them go, the moving will be kenetic energy
