Correct choices:
- J = FΔt (for a constant force; in general J = ∫F dt)
- J = mΔv (if mass is constant)
- J = Δp (always true: impulse equals change in momentum)
Why the others are wrong:
- F/Δt and m/Δt are divisions, not impulse.
- FΔv (force times change in velocity) is not a definition of impulse.
- J = FΔt (for a constant force; in general J = ∫F dt)
- J = mΔv (if mass is constant)
