Can there be displacement of an object in the absence of any force acting on it ? Think. Discuss this question with your friends and teacher.

Text Solution

Verified by Experts

Yes, there can be displacement of an object in the absence of any force acting on it. We know that `F = m xx a`. Now, when force F = 0, then `m xx a = 0`. Since mass 'm' cannot be zero, therefore, when force F = 0, then accelration 'a' = 0. In such a situation, either the object is at rest (not moving) or it is in uniform motion in a straight line. In the latter case, there is a displacement of the object without any force acting on it.
