The Good, the Bad, and the Ugly Physics  **__Good physics __ **2001: A Space Odyssey

This movie demonstrates Newton’s first law,  every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it,  perfectly. After Frank Poole (the astronaut in the space suit) is detached from his safety wire by HAL 9000, he goes flying off into space because he was going at a certain speed. Before the wire was keeping him attached to the ship, but now that he isn’t attached to the ship anymore he just keeps on going because there is no external force to slow him down/stop him.

[] **__Bad physics __ ** House M.D. In one Episode, Doctor House decides to step off of the balcony in a hotel that happens to be 6 stories tall. Within a few seconds it is shown that he is not trying to commit suicide, but rather do a cannonball into the hotel’s pool. He survives the fall without any injuries sustained to himself. To minimize impact He should have went feet first, but he did a cannonball instead. Also I find it hard to believe that someone who has had so many medical problems in the past, could fall that distance and not suffer any injuries. He steps off the balcony, so he has no initial velocity. He’s also 6 stories up, or approximately 60 feet in the air. Which is 18.3 meters. D=1/2at^2 +Vi*t 18.3=1/2(9.8)t^2+0 3.73=t^2 <span style="background-color: transparent; color: #000000; display: block; font-family: Times New Roman; font-size: 16px; text-align: left; text-decoration: none; vertical-align: auto;">1.93=t <span style="background-color: transparent; color: #000000; display: block; font-family: Times New Roman; font-size: 16px; text-align: left; text-decoration: none; vertical-align: auto;">Now that we have time we can use the formula <span style="background-color: transparent; color: #000000; display: block; font-family: Times New Roman; font-size: 16px; text-align: left; text-decoration: none; vertical-align: auto;">Vf=Vi+at <span style="background-color: transparent; color: #000000; display: block; font-family: Times New Roman; font-size: 16px; text-align: left; text-decoration: none; vertical-align: auto;">Vf=0+(9.8)(1.93) <span style="background-color: transparent; color: #000000; display: block; font-family: Times New Roman; font-size: 16px; text-align: left; text-decoration: none; vertical-align: auto;">So his final velocity is 18.93 meters/sec. That’s 42.4 miles per hour. House would have been hurt. <span style="background-color: transparent; color: #000000; display: block; font-family: Times New Roman; font-size: 16px; text-align: left; text-decoration: none; vertical-align: auto;"><span style="background-color: transparent; color: #810081; font-family: Times New Roman; font-size: 16px; text-align: left; text-decoration: underline; vertical-align: auto;">[]

This is ugly physics because by Newton’s third law, every action has an equal and opposite reaction, the girl shooting the gun would have also been sent flying backwards as well by the bullet leaving the gun. <span style="background-color: transparent; color: #810081; font-family: Times New Roman; font-size: 16px; text-align: left; text-decoration: underline; vertical-align: auto;">[] (start at 4:50, let it run for 20 seconds.)
