Which of the following best describes how the kinetic energy of an object changes when the net work done on it is negative?
(a) It decreases by an amount equal to the magnitude of the net work.
(b) It increases by an amount equal to the magnitude of the net work.
(c) It remains unchanged because only potential energy is affected.
(d) It decreases only until it reaches zero and cannot become negative, regardless of how much negative work is done.
