A force on a particle is conservative if ______?
Everyday Science / Physics — Multiple-choice practice
ایک ذرہ پر ایک قوت قدامت پسند ہے اگر ______؟
- A. It obeys Newton’s Second Law
- B. Its work depends on the end points of every motion, not on the path between them
- C. Its work equals the change in the kinetic energy of the particle
- D. None of these
Correct answer
Its work depends on the end points of every motion, not on the path between them
Explanation
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).
