Sticky Note
A force on a particle is conservative if ______?
ایک ذرہ پر ایک قوت قدامت پسند ہے اگر ______؟
  1. Its work depends on the end points of every motion, not on the path between them
  2. Its work equals the change in the kinetic energy of the particle
  3. It obeys Newton’s Second Law
  4. None of these
Explanation
  • A conservative force (e.g., gravitational or electrostatic) depends only on the initial and final positions, not on the path taken.
  • The work done by a conservative force can be recovered completely, unlike non-conservative forces (e.g., friction).
