is standing/walking/sliding possible on a frictionless surface?if answer is anyone tell me why?

Answer 1

newton's law state that for every force there is an equal and opposite force, thus to answer this question we must analyze each situation.
standing: your weight push down on the surface and it push back with normal force as this does not involve friction standing is possible on frictionless surface.
walking: to move in any direction u must push back (relative to u, that is, toward ur back) on the ground whose reaction force push u forward in desired direction. as this reaction force is due to friction u cannot walk on frictionless surface (ur feet will not encounter any resistance and will merely move in direction of ur exerted force ie back)
sliding: u can slide provided u have starting velocity; if u do not have starting velocity u cannot slide because there is no way for u to exert a external force forward or back or sideway with ur feet due to absence of friction. this of course is rectified if u have means to apply said force without using friction ie a rocket booster or something
hope this helps

Answer 2

Yeah, I would go with that smart SOB on this one. You can slip all you want, but you can't slide absent an external impulse.

Answer 3

standing - yes , it doesnt require any friction

walking - no, it requires friction so you can push yourself forward .. otherwise if you try to step, your standing foot will slipper back rather than you go forward

sliding - absolutely


... just imagine yourself on a very slippery ice

Answer 4

Only if you had another medium to act on you, like the air or little tiny jets built into you.
