A force On particle is conservative if:________?

A force On particle is conservative if:________?

A. It’s works equals the change in the kinetic energy of the particle.
B. It’s obeys Newton’s second law
C. It’s obeys Newton’s third law
D. It work depends on the end points of every motion, not on the path between.

A conservative force is a force with the property that the total work done in moving a particle between two points is independent of the path taken.
