    The integral of force (F) over the time period (t) for which it acts is called as impulse. Impulse is the product of force (F) and time (t). As force is a vector quantity, impulse is also a vector quantity in the same direction.

    The SI unit for impulse is Newton x Second (Ns)

    A force applied on a body causes acceleration, as long as force is acting on body. The large resultant force applied on a body for a short period of time can produce same momentum as when a small resultant force applied on the body for longer period.
