It is better to not get hit in the head but sometimes it just ends up that way. Hockey helmets are designed like most helmets with the ability to absorb most of the energy from impact. The thing that I believe separates a hockey helmet from a standard football helmet is the fact that the top of the line hockey helmet rotates a little around your head without jerking your head in the initial impact. (I don't Know enough about football equipment to speak on behalf of the equipment) However, most i
A human body has the ability to release a huge amount of strength through its muscles. The reason that a person is unable to unlock all of this strength at any given time is so that muscles do not get strained or torn in the process. This is a cool safety feature of the body so that people do not over exert themselves and end up crashing. In order to produce large amounts of strength it takes a lot of energy and using muscles to their max for a long period of time can be very harmful to the body
So as we all know there is no gravity in space so, what would happen when you want to wring out a wet towel there? I fond this question very interesting when talking with friends so I thought I would take a deeper look into it. When you have a very wet towel and go to wring it out, the water is not just going to fall off like it does on earth. Instead because of the waters surface tension and lack of gravity in space, the water will float around the surface of the towel forming a tube shape ar
So on the back of super cars you often find a spoiler. As a kid I always thought that a spoiler was just to make the car look cool but in fact it does serve many purposes depending on the positioning and type of spoiler used. One use of a spoiler is to push the air around behind the car as the car pushes through the air this reduces the drag force on the car. This application of the spoiler can improve gas mileage. Another reason why spoilers are seen on super cars is because when traveling a ve
In order for a monster truck to be able to do a front flip it needs for one of its points far from it's center of mass to come into contact with a fixed object. One way of doing this would be to get the truck into a wheelie or almost stand the truck up, then you need to hit a fixed object like a very steep jump. This will cause for the truck to begin a rotational motion and begin to do a front flip. This is because the impact of the tires on the fixed surface act as a torquing force which cause
Through photon camp in which I attended last year there was a lot of talk about lasers. This is because while using optics you can do a lot with lasers this is because you are easily able to manipulate them. The three things that all lasers have are an energy source, a medium and a resonator. The energy source or source pump is used to provide the laser with the energy that it needs to be powered. The medium is what really separates lasers because it determines the strength of the laser or the p
