Document Summary
Armageddon! (at the top of the list for a reason) Mel gibson, schwarzenegger, james bond movies: interesting case study: armageddon vs. Deep impact hired science consultants and did okay: themes of physics misrepresentation, everything goes boom, and explodes in huge fireball. Real life more often just crunches (we"re not loaded with dynamite: momentum seldom conserved. Bullet sends victim flying out window, shooter remains motionless: hearing sound in space. No air to carry sound waves: seeing laser beams in space. Is it smoky: aerodynamic spaceships, airplane-like maneuvering, exploding rather than imploding submarines, fake props: wrong inertia properties. Raiders of the lost arc: swiped huge gold statue like it was nothing: movie examples , goldeneye, catch up to airplane. Terminal velocity of human: 50 m/s, up to 70 m/s if you reduce your effective area by a factor of two. Terminal velocity of plane in dive configuration: about 90 m/s (more with engine at full power)
