Let F(X) be a conservative force. Under this force, a particle is displaced from the initial position X_i to final position X_f. Which of the following relations are correct?

(a) _Xi

^Xf F(X) dX = K_f - K_i(b) K_i + U (X_i) = K_f + U (X_f)

(c) - _Xi

^Xf F(X) dX = U (X_f) - U (X_i)

(d) | K_f - K_i | = | U (X_f) - U (X_i) |
