    Why is it easier to push a heavy block from behind than to press it on the top and push?
    Ans :
    It is easier to push a heavy block from behind than from the top because when we try to push a heavy block from the top, we increase the normal reaction force, which, in turn, increases the friction between the object and the ground (see the figure).
