The impulse delivered to a body is numerically equal to its
ATotal kinetic energy
BRate of change of mass
CAverage acceleration
DChange in momentum
Answer & Solution
Correct answer: D. Change in momentum
1. Impulse J = F x t.
2. From the second law, F x t = change in momentum, Δp.
3. Therefore J = Δp, so impulse equals the change in momentum, with the same unit kg m s⁻¹.
