Conservative force (±£ÊØÁ¦)
|
A force is a conservative force if the net work it does on a particle moving along a closed path from an initial point and then back to that point is zero. Or,equivalently, it is conservative if its work on a particle moving between two points does not depend on the path taken by the particle.

Conservative or nonconservative? |
Example: The force on an electron is F=Cxj, where C is a positive constant. The electron moves in a counter-clockwise direction around the loop shown in the figure. Calculate the work done on the electron. Is this force conservative or not?
