Question

Which of the following statement is correct about non-conservative force?

• A. It depends on velocity of the object.
• B. It depends on the particular path taken by the object.
• C. It depend on the initial and final positions of the object.
• D. Both(a) and (b)

Answer 1

Answer: (D)

If the work done or the kinetic energy depend on other factors such as the velocity or the particular path taken by the object, the force would be called non-conservative.
Thus, the statements given in options (a) and (b) are correct, rest is incorrect.
