Can you associate potential energy with a non conservative force ?

Text Solution

AI Generated Solution

To determine whether potential energy can be associated with a non-conservative force, we need to analyze the characteristics of conservative and non-conservative forces. ### Step-by-Step Solution: 1. **Definition of Non-Conservative Forces**: Non-conservative forces are forces for which the work done depends on the path taken, rather than just the initial and final positions. Examples include friction and air resistance. 2. **Path Dependence**: ...

These questions consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following five reponses (a) If both Assertion and Reason arecorrect and Reason is the correct explanation of Asserrtion. (b) If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion. (c ) If Assertion is true but Reason is false. (d) If Assertion is false but Reason is true. Assertion If work done by conservative force is negative, then potential energy associated with that force should increase. Reason This is according to the relation DeltaU=-W Here, DeltaU is change in potential energy and W is work done by conservative force.

(b) If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion. (c ) If Assertion is true but Reason is false. (d) If Assertion is false but Reason is true. Assertion Spring force is a conservative force. Reason Potential energy is defined only for conservative forces.

Assertion: When two unlike charges are brought nearer, their electrostatic potentiasl energy decreases. Reason: All conservative forces act in the direction of decreasing potential energy.

Which one of the following is a non-conservative force ?

Is friction , a conservative or non-conservative force ?

Answer the question briefly and the point: Friction is a non-conservative force. Why?

A : The potential energy of a system increases when work is done by conservative force. R : Kinetic energy can change into potential energy and vice-versa.

STATEMENT-1: Work done by the net force acting on a particle is equal to the change in its kinetic energy. STATEMENT-2: Change in potential energy is always equal to the work done by external forces. STATEMENT-3: Work energy theorem is not applicable, if the work is done by the non-conservative forces

(A) : When a body moves on rough surface the mechanical energy is not constant (R) : Friction is non conservative force
