Wow! Physics!

A burnout is an example of friction, a large part of physics. A burnout occurs when a cars engine turns the wheels harder that the level of friction the tires of the car can hold. Once that level is reached the tires break traction and start to spin, as the tires spin faster and faster they heat up starting to burn the tire creating smoke which is what you see above.

This picture of a snow plow relates to physics in how the truck is pushing snow that has a lesser mass and "oomh" than the plow truck which is why heavier trucks can push more snow.

Here we have a picture of a man doing a hand stand on a motorcycle. This is a prime example of physics and how the rider is traveling at the same speed as the motorcycle is and is what makes this stunt very difficult and very dangerous. The proper way to do this stunt is to be extremely steady and keep as much of a persons weight lowest to the bike to keep the center of gravity low. This relates to physics in areas such as gravity, wind resistance, center of gravity and constant velocity.  

You know, with the whole centripetal force. Yeah that was probably my weakest section.

Everyone recognizes when a momentum collision happens between two cars, but it also happens in sports. In this picture, we see that after two football players collide with each other, one football player is going forward and pushing the other back. This is an example of two forces using momentum against each other. Whether it's because the football player, moving forward, has more mass or speed, he had momentum allowing him to push the other football player.

When you go to the gym and do a warm-up set on bench press, you're actually pushing up way lass than you normally do. Now, you may think that when it comes to who is exerting more force between you or the barbell, it you because it's not heavy. WRONG! In actuality, you and the barbell with weights are exerting the same amount of force, according to Newton's 3^rd Law, which says the forces of two bodies on each other are always equal and are directed in opposite directions.

When two people who are most likely similar in weight are racing, they exert force for a certain distance. Therefore they produce work. One runner finishes first, so you would think that he did more work than the other runner. What is interesting is that they produced the same amount of work. It is power in fact that the faster runner exerted more in. When it comes to power, time becomes a factor. So, since the faster runner finished in less time, he exerted more power than the other runner.

In the long throw performed by track and field athletes, the athlete uses centripetal force to propel the object as far as they can. Since the objects velocity is always changing, the athlete has to let go of the object at the proper time in order to properly aim for the trajectory.
