Define impulse .

Answer»

Solution :A large force acting for a very short interval of time is called as .Impulsive force.. When a force F acts on a body for a period of time t, then the product of force and time is known as .impulse. represented by .J.
`"Impulse, J"=Fxxt"(1)"`
By Newton.s SECOND law
`F=Deltap//t""(Delta" refers of change")`
`Deltap=Fxxt"(2)"`
From (1) and (2)
`J=Deltap`
Impulse is also equal to the MAGNITUDE of change in momentum. Its unit is `"kg MS"^(-1)` or Ns.
