Change in momentum when a force acts over time
I=F×tI = F \times tI=F×t
I=mv−muI = mv - muI=mv−mu
Yes, direction matters - use positive/negative signs
Newton-seconds (Ns) or kg m s−1^{-1}−1
I=∫0tF dtI = \int_{0}^{t} F \, dtI=∫0tFdt
Impulse always equals change in momentum
Impulses are equal in magnitude but opposite in direction
Zero (no friction, so momentum conserved in that direction)
When force varies with time (not constant)
