Conservative Force

Potential Energy Concept|| Relation Between Conservation Force And PE

STATEMENT-1 When a conservative force performs positive work on a body, potential energy of the system decreases. STATEMENT-2 Work done by a conservative force does not produce any change in kinetic energy.

Identify conservative and non-conservative forces given below and write one main difference between them on the basis of work done : frictional force, electrostatic force, gravitational force and viscous force.

A particle is moving in a conservative force field from point A to point B.U_(A) and U_(B) are the potential energies of the particle at point A and B and W_(C) is the work done by conservative forces in the process of taking the particle from A and B, which of the following is true?

A force is said to be conservative if work done by or agains the force depends only on initial and final positions of the body and not on the nature of path followed. A force is said to be non-conservative, if work done by or against the force in moving a body from one position to another, depeds on the path followed between these two positions. Potential energy is defined only for conservative forces. It does not exist for non-conservative forces. Read the above passage and answer the following question : (i) Give two examples, each for conservative and non-conservative forces. (ii) Potential energy does not exist for non-conservative forces. What does it imply ini day to day life ?
