    bcoz they act on different objects.

    as newton`s third law say...'every force has an equal and opposite reaction..'

    so to cause a reaction a force must first act....

    that means reaction will take place only after action....

    they dont exist together, so they wont cancel each other...

    just consider a rocket taking off...the thrust from its burner(action force)..the reaction force by the ground on the rocket(reaction)...which is after the thrust....

    Due to gravitational force every object pull by the earth at 9.81 m/sec,so forces and sizes are not a matter,but, if the objects had center of gravity, they can be balanced.

    Reaction will take place only after action. for instance you can consider a book on the table again a car travel on the road.

    I agree with sidchavu, the two forces are acting on two different objects. Each object experiences just one of the forces, and will accelerate.

    "why aren't they balanced for"...for what?
