Projectile Motion Photo


This picture is of a swimming backstroke start. It represents projectile motion because of the parabola shape. In this case the parabola is opening down. For a backstroke start the arched back with the feet following up on the whole body's motion creates the parabola. Right at the beginning the first push the velocity 9.8m/s and continues until the peak of the start where the velocity it Om/s because she is not going up or down. Then eventually starts going down with the velocity again at 9.8m/s.

Projectile Motion Phot Projcet

This tiger leaping is just one example of a projectile's motion. A projectile's motion first goes up and then eventually comes down, because everything has a velocity of 9.8m/s. The tiger's initial velocity is 0 m/s, because he was at rest before he leaped into the air. Once he's in the air his velocity changes every second by 9.8 m/s. Then when the tiger reaches it's peak it has a velocity of 0 m/s for that one second becasue he is neither falling or going up. Then the tiger's velocity changes by 9.8 m/s again until it lands on the ground.

Phaulty Physics in Philm: Family Guy

In this clip of Family Guy, Peter rides a dragon. Then, due to Peter's weight, the dragon goes down as a free-falling object. The dragon is flying at the height of the mountains in the background. These mountains are aprroximately at the height of the clouds. Clouds above ground level are from 3000-8000 meters above sea level. Lets say the dragon is approximately at 4000 meters high. It would take him approximately 28.57 seconds to fall. (I figured this out using the solving for time formula.) In the video, he falls for only 2-3 seconds. The cartoonist was about 25 seconds off. which means he had a error yield of approximately 88%. This goes to show that Family Guy was way off with the laws of Physics on this one.

This clip defies the laws of physics because an objecet fallings is suppose to have a velocity of 9.8m/s and the baby keeps walking on air without falling. You can see the wooden board being pulled from under the baby while hes crawiling on it and yet when there's no board left he is still in the air. If any other object where to be on top of a board and that board where to be pulled out an object should usually fall at a 9.8m/s velocity but in this case the baby is still suspended in the air. We chose this video because is shows the "phaulty physcics" of how a baby is still crawling in the air with no support with out falling.
