I'm a big fan of guns. I love shooting them and i love the eminence power they posses. Guns are really amazing machines, for being so little and simple they pack a punch. Mechanical reactions are what make guns guns. When shooting a handgun, once the trigger is pulled, the hammer falls down with tremendous speed and strikes the primer. The strike causes a spark which then ignites the gunpowder. The explosion form the gunpowder propels the bullet out of the gun at high speeds. It is quite incredible how something so little and compact can do something like this.

So you get in a fight and your gettin ready to throw a punch, you know you gotta hit hard and ya gotta hit fast, but do you know the physics of a punch???? The physics of a punch is actually much more complicated then one may think. The arm acts as a lever while ya fist and your body deliver the power. While it is quite obvious that you can find the force using F=Ma, there's much more to it. A good punch requires the whole body, not just ya arms. By rotating your hips and legs, you can pack a much bigger punch. The rotation generates more force and by delivering the punch and driving your hand threw the target, your punch will be much more powerful. If you ever find yourself in danger and need to throw a punch, make sure you throw your whole body into it, you don't want to be catching hands, you wanna be delivering them.

Catapults are so cool!!!!!!!!!!

The hook grip is the best way to grip a barbell for the snatch and clean and jerk movements. To perform the hook grip, the lifter must first wrap their thumb around the bar, once they have their thumb in place, they then wrap their remaining fingers around the thumb and bar. This hook grip is much stronger than a regular grip. As the weight gets heavier, the hook will be your savior!!! The hook lessens tension in your forearms and makes it easier for you to perform the pulls and hip drives. The use of a death grip is no longer needed because of the hook grip. The grip may beat ya thumbs up a little bit and feel very uncomfortable, but with continued use of the hook grip, your hands will toughen and your PRs will soar!!!!

Gronk sure is a big guy!!!!!!!!

The snatch is a very complicated Olympic weightlifting movement. The movement is very difficult and often takes months of training to master it. To perform a snatch the lifter must squat down, grab the barbell with a wide grip using the hook grip. The hook grip is the best way to grip the bar. After the Lifter has gripped the bar, they then keep their head and chest held high while down in the squat position. When the lifter is ready they then pull the bar up along their body, once it reaches hip level, the lifter pops the bar off their hips with tremendous force sending the bar up past your head. Immediately after popping the bar of their hip the lifter drops below the bar into a squat position and catches the bar over head. Once the bar is caught and the lifter feels balanced, they must stand up with the bar over head, arms locked out, and knees straight. Once the lifter does this the lift is complete. The snatch requires a lot of power and explosiveness. The initial pull of the bar off the ground can be considered the most important part of the movement. If the pull is too fast, the bar will go to far over your head and you will more than likely loose balance and fail the lift. If the pull is not fast enough, the bar will not go high enough and the bar may very well fall on your head, OUCH!!!! Along with the bar speed, the speed at which you drop under the bar is very important. When you watch Olympic athletes snatch, you will see them snap under the bar with tremendous speed and bring the bar to a halt very quickly. The snatch is all about speed and explosiveness, with the proper technique and training anyone can become a master of the snatch.

So a couple years ago a good friend of mine got his cat stolen! While I'm not very fond of cats at all, i felt very bad for my friend because he loved his cat. Looking back at it now i wonder the amount of work put in to steal a cat. The average cat weights about 4.04 kg, or 8.9 lbs for us Americans. So lets say the catnapper was a master of stealth and snuck up on our feline friend, they would have had to grab the cat and pull it quickly of the ground. The average height of a person in North America is about 1.69 m so they would have to pull the cat to lets say chest level which would be around 1.48 m. To pull the cat off the ground to chest height it would be about 59.8 joules of work, id say that's just too much work for a cat, just go buy a dog.

Hydraulic fracturing is the future. Hydraulic fracturing or other wise know as hydro-fracking is a process used to obtain natural gas from deep down in the earth. A drill is first used to drill deep down into to earth and then horizontally for about 8000 ft each way. 6-8 million gallons of water and a small amount of other chemicals are pumped down into the ground with such force that it breaks rocks and other earth materials containing natural gas. One of the major drilling sites is the Marcellus basin deposit , this deposit contains a tremendous amount of natural gas, equivalent to 80 billion barrels of oil, that's a lot of gas!!!!!!! Hydro-fracking can gives us huge amounts of energy, it will decrease the cost of living and will have a great affect on today's economy.

WOW! must have been a lot of work to put that in the game.

nice!!!!!!!! WAW is so fun, great post guy!

The clean and jerk is an Olympic weight lifting movement where the lifter pulls the the bar from the ground, catches it in a squat, stands up from the squat and thrusts the bar over their head. The clean is performed by pulling on the bar off the ground with a high velocity, once the bar reaches about chest height, the lifter drops under neath the bar and catches it on his shoulder, and sits in a low squat position. The lifter then pushes up with a high velocity to stand back up, this is the clean. The jerk part of the movement is fairly simple. The lifter dips their hips down how ever far they desire, then they thrust the bar up with a high velocity, kick their legs out in a lunge position, catch and hold the bar at rest above their head.

Very cool, its interesting to know about the physics of something i do almost everyday!!!! GO STEELERS!!!!!!

Counter Strike Global Offensive, or CS:GO for short, is a competitive PC shooter game where 2 teams of 5 fight over an objective with only 1 life each round. While CS:GO is very fun and competitive, it also has some very interesting physics to the game. In The game some of the more powerful weapons are able to shoot through different materials, some being wooden doors, large creates and even other players. Depending on the weapon used, the damage through the material changes, for example, if you were to use the high powered AWP sniper rifle it would due a heck of a lot more damage then say a standard M4-A1s rifle. Another thing you can do in the game is bounce grenades off walls, doors, etc.. When you throw the grenade you have three different ways to throw it, underhand for short tosses, overhand for those long throws, and a mix between the two when ya don;t quite need the extra distance. Depending on how hard you throw the grenade, the amount of times and power the grenade hits the wall changes. When you throw it harder it may bounce of more walls or go further when you bounce it off a single wall. Along with these physics there's a exploit to the games engine where you can perform a maneuver referred to as "bunnyHopping" . A bunnyhop is performed by air-strafing back and fourth or left and right. It takes a very skilled player to be able to pull a bunyhop off but once mastered you are able to bunnyhop around the map, which increases your velocity every-time you land a hop. This only works because at a certain time in the air right as you land, there is no friction, if you time up the movement you can then bunny hop again and some how avoid any friction which will make you faster and faster. While CS:GO isn't a physics based game, the physics in the game make it unique and a fun experience.

nice work mike!!!!! Keep it up!!!!!
