Question

Which of the following is NOT an Aristotle’s concept about motion? *

A. Motion can be natural or violent.

B. An object will move if an external force is applied.

C. The motion of an object is parallel to the ground until it is the object's time to fall back into the ground.

D. An object in motion, if unimpeded, will continue to be in motion; an external force is not necessary to maintain the motion.
