Airbags reduce injury because they
A.increase the stopping time, reducing the force
B.reduce the change in momentum
C.increase the change in momentum
D.remove all force from the collision
Explanation
Core Concept
The same Δp spread over a longer Δt lowers the average force (J = FΔt).
Correct Answer
Aincrease the stopping time, reducing the force
