Two equal and opposite forces cancel out if they are applied to the
same body, and they do NOT cancel out if they are applied to two
different bodies.
So, if a horse, harnessed to a cart that's too heavy, can't get it
moving despite all its efforts, it means that the horse's forward
force F1 is canceled out by the backward force F2 of the cart, exactly
as if the two forces F1 and F2 were acting on the same body and not on
two different bodies.
Does this happen because the horse and cart, when harnessed, are
effectively a single body?
