How much potential energy is stored in a tied shoelace?
No. the two works are unrelated.christianjb said:You can work this one out by measuring the work done it takes to undo the knot.

I guess that it's nowhere near a conservative force field, so most of the work is done against friction, which ends up heating the shoe-lace.
Potential energy is the energy that an object possesses due to its position, shape, or state. It is stored energy that has the potential to do work in the future.
The potential energy of a shoelace is the energy that is stored when the shoelace is stretched or bent. It is a type of elastic potential energy.
A shoelace has potential energy when it is stretched or bent because of its elastic properties. The energy is stored in the stretched or bent molecules of the shoelace, which can be released when the shoelace is untied or straightened.
The potential energy of a shoelace can be calculated using the equation PE = 1/2kx^2, where PE is the potential energy, k is the spring constant of the shoelace, and x is the displacement of the shoelace from its equilibrium position.
The potential energy of a shoelace is affected by the amount of stretch or bend in the shoelace, the material and thickness of the shoelace, and the force applied to the shoelace. The greater the stretch or bend, the higher the potential energy will be.
