Question

a) State the relation between a conservative force and potential energy.

b) Derive the expression for the potential energy stored in a spring of spring constant

-

when it is stretched by an amount x.​

Answer 1

Answer:

a) Potential energy is the energy a system has due to position, shape, or configuration. It is stored energy that is completely recoverable. A conservative force is one for which work done by or against it depends only on the starting and ending points of a motion and not on the path taken.

sorry I don't know b one

Answer 2

A)

Potential energy is the energy a system has due to position, shape, or configuration. It is stored energy that is completely recoverable. A conservative force is one for which work done by or against it depends only on the starting and ending points of a motion and not on the path taken.

B)

Let a spring of spring constant ‘k’ is stretched through a distance ‘x’ by the application of force fext.  Let x = o is the normal posting then the restoring force vector F brings the spring to its normal position.
