Impact

Impact is ubiquitous in everyday life — everytime we see bodies collide, impact is applicable. In sports, bats hit balls and cues hit billard balls. In construction hammers hit nails and in auto “accidents” cars impact each other.

In space science, near-Earth objects are studied with “impactors” that eject debris so that their composition can be studied. Fixed-wing and rotory-wing vehicles need to worry about bird strikes, sand and dust, and even anti-aircraft artillery in combat zones — all examples of impact.
