Question

The net force on a moving object suddenly becomes zero. The object then (A) stops abruptly (B) stops during a short time interval (C) changes its (D) continues to move​

Answer 1

Answer:

The object retains its movement as it was at that moment. If the body was at rest it will remain at rest. If the body was moving at a velocity \vec V

V

, it will continue to move at the same velocity in the same direction. This behavior corresponds to Newton's first law, which States: "In an inertial frame of reference, an object either remains at rest or continues to move at a constant velocity, unless acted upon by a force". Newton published this law in 1726.

In those days, most people believed that the object does not experience any force will gradually stop and come to a state of rest. This erroneous judgment seemed to fit with common sense, since all bodies stop sooner or later if nothing pushes them. And only the outstanding scientists of that time realized the fact that the cessation of movement is due to the ubiquitous presence of the force of friction between moving objects.

In real life, a similar event of sudden termination of the force can be observed when throwing a spear, hammer, or core by an athlete. When an athlete releases a projectile from his hands, it continues its movement in the same direction and at the same speed as the athlete's hands moved it.
