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 can analyze the definitions and characteristics of both concepts. ### Step-by-Step Solution: 1. **Define Potential Energy**: - Potential energy is the energy stored in an object due to its position or configuration. It is energy that can be converted into kinetic energy or work when the object is allowed to move. 2. **Characteristics of Conservative Forces**: ...

  • This section contains Assertion and Reason type questions. Each question has 4 choices (1), (2), (3) and (4), out of which only one is correct. Assertion (A) If work done by conservative force is negative, then potential energy associated with that force should increase. Reason (R) This is from the reaction /_\U=-W Here, AU is change in potential energy and W is work done by conservative force.

    A
    Both Assertion and Reason are correct and Reason Is the correct explanation of the Assertion
    B
    Both Assertion and Reason are correct but Reason Is not the correct explanation of Assertion
    C
    Assertion Is correct but Reason Is Incorrect
    D
    Reason is correct but Assertion Is Incorrect

  • Consider the following statements and choose the correct option. I. Potential energy is a conservative force. The change in potential energy is equal to the negative of the work done by the force.

    A
    I and II
    B
    Only I
    C
    Only II
    D
    None of these

  • 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.

    A
    If both Assertion and Reason are true but Reason is the correct explanation of Assertion.
    B
    If both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
    C
    If Assertion is true, but the Reason is false.
    D
    If Assertion is false but the Reason is true.

    Relation Between Potential Energy And Conservative Forces

    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 ?
