A) a scalar
B) equal to change in the momentum of a body
C) equal to rate of change of momentum of a body
D) a force
Correct Answer: B
Solution :
Impulse is given by the product of force and time. From Newton?s second law \[F=ma=m\frac{\Delta V}{\Delta t}\] \[\Rightarrow \] \[F\,\,\Delta t=m\,\,\Delta V\] = change in the momentum of the body.
