Catch a raw egg by stopping it dead and it bursts; let your hand ride backward and it survives. The momentum change was the same either way — all you bought was time.

By the end
- 01Compute momentum as a vector and model collisions and explosions as brief events dominated by internal forces
- 02Compute impulse from an average force and a time interval, or as the area under a force–time graph
- 03Apply the impulse–momentum theorem, including net force as the slope of a momentum–time graph
