Can there be displacement of an object in the absence of any fore acting on it?

Answer 1

of course. there can be displacement of an object in the absence of any force acting on it. this is because,

for an example ,

when we he keep the ball or any other object in the inclined plane or in the slanting surface it move to the another point that is displacement without any external force acting on it.

so there can be displacement without any force acting on it.

================================

Poor example. A ball on an inclined plane or any slanting surface has gravitational

force on it, pulling it down the slope.

A better example, related to daily life on Earth, is a ball rolling across the

Basketball court on the perfectly level floor. Sure, there's still a gravitational force

on it, but the force is not in the direction it's moving, so gravity isn't helping it

move. In fact, there's no force at all helping it move, and yet it continues to move.

This is Newton's first law of motion ... a statement so simple and so completely

opposite to everything we see in our daily life that nobody except Physicists can

understand it, and nobody except Physicists knows how to use it. It simply says

that no force is necessary to keep a moving object moving.
