1. Identify conservative and nonconservative forces given below and write one main difference between them on the basis of work done. 2.Frictional force, electrostatic force ,gravitational force and viscous force
A conservative force is one for which the work done is independent of path. Equivalently, a force is conservative if the work done over any closed path is zero. A non - conservative force is one for which the work done depends on the path
Gravitational force/ electrostatic force =If the work done by a force depends only on initial and final positions, not on the path between them, the force is called a conservative force that why gravitational force is conservative force in electrostatic force there is movementsof charge (electon).
friction force/viscous force =these type force resist path of motion and in viscous there is movement of liquid
I hope it will help you
Thank you
