Question

The force a spring exerts on a body is a conservative force because the work a spring does on a body is equal and opposite for compressions and extensions of equal magnitude. the work a spring does on a body is equal for compressions and extensions of equal magnitude. a spring always exerts a force parallel to the displacement of the body. a spring always exerts a force opposite to the displacement of the body. the net work a spring does on a body is zero when the body returns to its initial position.

Explanation / Answer

conservative forces does negative work on the body, here also the body will also exert force (as forces are mutual and is attributed to Netwon's 3rd law, law of gravitation,Coulomb's law...) on the agent of the forces(earth,charge) & will do positive work on them. But instead of gaining that work , it is stored as potential energy. Thus though the body loses energy ,the agent doesn't gain that.

SPRING FORCE

Therefore, the work done by the spring on the particle depends only on the position of A and B (relative to the position of point O), since this is what determines the amount of stretch or compression in the spring (s1and s2). Therefore, an elastic spring is a conservative force.

Knowing if a force is conservative is very useful for solving problems using energy calculations, since you only have to know the initial and final position where the force is acting. You don
