Multiple Choice

Marcy is driving on a road parallel to train tracks at a constant velocity. At the same time, a train is accelerating in the opposite direction at a rate of 5 . Marcy hypothesizes that if her car was not moving, the train would appear to accelerate at a slower rate.

Upon which scientific principle has Marcy based her hypothesis?

• Objects in motion have a tendency to maintain their motion.

• For every action, there is an equal and opposite reaction.

• Energy tends to become more disordered with time.

• All motion is relative to a frame of reference.

Dropdown
