Accroding to Newton's law of interaction, for every force you exert on an object , the object also exerts an eqaul but opposite force on you. Will it be possible for you to accelerate the object in view of this equal and opposite forces?

1.) depends on the object in question and what other forces are at play - wind resistance, static friction, structural resistance relative to a common connection (like the Earth), etc.,...

2.) assuming these external forces are canceled for arguments sake, then the answer is yes - you can accelerate an object.

HOWEVER - the acceleration only happens as long as a forces is applied to the object. the moment you loose contact with said object, you are no longer applying force to the object (in the case of pushing or throwing for arguments sake).

you accelerate the object as you apply force but then the object is subject to newton's laws the moment you loose contact - IE - it stays at its current state of motion until an external force acts on the object.

you as the 'force' are also pushed back at the same rate. If you are more massive than the object (again neglecting resistance such as friction) you will accelerate the object more than it is accelerating you in the opposite direction. If you are less massive, you will be accelerated in the opposite direction more than the object.

either way, the objects motion state will change, that implies an acceleration of some type. acceleration being defined as a change in motion - speeding up, slowing down or changing direction all are changes in motion.

If you have a mass of 100g and push on something that has a mass of 50g, it will move because it doesn't have as great of a mass, although the forces are the same on both you and the object.

It depends on inertia - if you push on a wall with 1 pound of force, it pushes back with 1 pound of force. If you push on the wall with 1,000,000 pounds of force, you will accelerate the wall right through your house.

Ravi is authentic. in case you hit a ball, you exert some rigidity on the ball and the ball exerts a similar rigidity on you. because you're heavier than the ball and on account that a=F/m, the ball hurries up better than you do. once you leap, you quite exert a rigidity on earth. yet now the Earth is way heavier than you're so that you boost up better. the most illustrative get jointly should be too skaters, status in the front of one yet another and pushing. they're going to now both be speeded up, in opposite guidelines. you ought to word that both-skater-gadget which includes both skaters as one merchandise gained't get speeded up. Their hardship-loose middle of mass does not flow. So certainly, you may not boost up your self via pulling your self via your hair or kicking your human being yet, because the rigidity exerted on your yet will be neutralized via an equivalent and opposite rigidity on your foot. yet via exerting the rigidity on another merchandise, you may boost up your self.
