action and reaction forces do not balance each other. why?
they do not balance each other because they act on different bodies for eg- if you are pushing a car then a force is acting on the car similarly the car is also pushing you or applying a force on you and the force is acting on you....so here you and car are two different objects!!...............hope this will help you!
Action and reaction forces act on different bodies, but mostly of different masses as well.
Eg: When I push a car, i exert action force on the car, but it has a greater mass than me so it doesn't move. The car in turn exerts a reaction force on me but since I exert a force on the ground to stand firm, the equal reaction exerted on me does not displace me.
Hope I cud help!
