A) objects cannot change or move unless acted upon by outside forces.
B) change is continuous.
C) time unquestionably moves in one direction.
D) none of the above

Question

Quizplus · Accepted Answer

None of the options are completely true based on modern physics. A is not true because objects can exhibit motion without being acted upon by an outside force (for example, an electron in an excited state undergoing a spontaneous emission). B is not always true because some changes can happen instantaneously (such as in the case of quantum entanglement). C is not entirely true because there are phenomena in physics that violate the arrow of time (such as in certain interpretations of quantum mechanics).
