Answer:
Impulse is a vector quantity.
Explanation:
The force acting for a very short interval of time is called impulse. It is also equal to the change in momentum of an object for a very short time. It is represented with letter J. Its SI unit is Newton-seconds or N-s.
Impulse is a vector quantity i.e. impulse has both magnitude as well as direction. Its direction is as same as the direction of applied force. Mathematically, it can be written as :
\(J=\int\limits{F} \, dt\)
Hence, the correct option is (2) "impulse ".
