OpenStudy (mayankdevnani):
Can there be displacement of an object in the absence of any force acting on it?
Justify your answer.

OpenStudy (mayankdevnani):
why?

OpenStudy (mayankdevnani):
and how?
OpenStudy (anonymous):
U know Newton's first law of motion?
OpenStudy (anonymous):
I guess u don't need force to keep something in motion once it's started.
OpenStudy (mayankdevnani):
law of inertia
OpenStudy (anonymous):
Ignoring friction and all sort of thing...

howz that
OpenStudy (mayankdevnani):
but to displace anything we need force
OpenStudy (mayankdevnani):
An object remains in rest or in uniform motion in a straight line unless compelled to change that state by an applied force
OpenStudy (anonymous):
Actually no. Once u applied Force and remove the force. The object will have constant velocity.

And velocity means there is displacement.
OpenStudy (anonymous):
kinematic
OpenStudy (mayankdevnani):
but answer is yes
OpenStudy (anonymous):
Without friction, air resistance etc (otherwise there are forces acting)
OpenStudy (mayankdevnani):
so what's the answer

OpenStudy (mayankdevnani):
thnx...... @sauravshakya
OpenStudy (anonymous):
The answer is YES.
OpenStudy (anonymous):
The answer is yes provided that you ignore frictional, resistance, gravitational forces
(ie it is a completely unrealistic scenario)
OpenStudy (mayankdevnani):
ok i got it
