A man is pushing a car. It is moving . But according to Nuton's third law it can not happen. Because it says every action has an equal and opposite reaction. That means when man pushes the car in turn car pushes the man. So forces get cancelled then and there, in which case there is no possibility to move the car. What is happening here ? . Is the Nutons low wrong ?

Question

anonymous · Answer

It's Newtons law.. :)

anonymous · Answer

Well when moving it acts according to Newtons 1st law..

think net force

anonymous · Answer

The possibility of the car not moving only when the force applied to the car does not exceed the frictional force between the car and the ground. However, after the force exceeds the frictional force, the car would then accelerate and there would be a force applied on the car.

To "cancel one another", two forces would have to act on the same object. The action-reaction forces we talk about with Newton's Third Law or the forces in this question act on different objects.

Law states   "equal & opposit )

zzr0ck3r · Answer

two different objects.

anonymous · Answer

As zzz said. Newton's third law shows an equal and opposite reaction force acting back at you from the object. Get the 'giver' and 'receiver' right.
