Impulse Is the Area, and the Bounce Costs Double
A ball that bounces straight back takes twice the impulse of one that sticks — the reversal runs its momentum all the way from +mv to −mv. Watch the force-time graph shade itself in, learn why an integral (not peak × time) reads a varying force, and why every airbag is just trading time for force at a fixed Δp.
