Only if a force on a particle is conservative:
A)does it do no work when the particle moves exactly once around any closed path
B)does the work it does equal the change in the kinetic energy of the particle
C)does it obey Newton's second law
D)does it obey Newton's third law
E)it is not a frictional force

Quizplus · Accepted Answer

This is a property of conservative forces known as the conservation of mechanical energy. The work done by a conservative force only depends on the initial and final positions of the particle, not the path taken between them. This means that if a particle moves in a closed path and returns to its original position, the total work done by the conservative force over the entire path is zero.
