Are normal reaction and tension conservative ?
Consider the case of a plank (with a block on it ) at rest on the floor.
the work done by normal reaction is zero.
Now imagine a man pushes the plank upward with an acceleration.
Now the work done by normal reaction is nonzero.
can normal reaction in the second case be considered non conservative.
A similar situation is the case of a body at the lower end of a rope being
pulled vertically upward by a man moving the upper end. could we label
tension as non conservative?

I think it depends on what forces are causing the normal reaction and
tension(like when two masses are hanging on the opposite sides of a
forcethen the tension in th rope is due to gravity which is a conservative
____________________________________________________________________________and so the tension is conservative).
Is this right?
