## Physics in Counter Strike Global offensive (CS:GO)

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

## Physics of dribbling a basketball

Everyone dribbles a basketball at some point of their life, but have you ever stopped and thought about the physics of dribbling one? When the ball is in contact with your hand it builds up potential energy. When you apply a force to the ball and begin dribbling it transfers the potential energy of the ball into kinetic energy. As the ball collides with the floor, the floor the pushes the ball back up to your hand. This is because of Newtons 3rd law: with every reaction there is an opposite and

## Physics of standing up

Standing up can be hard sometimes and I personally prefer laying down, but you know life goes on and everyone needs to stand from time to time. So how exactly does standing up work? Say you are sitting down in your computer chair reading this blog post and you suddenly feel very thirsty and want to get up and get a glass of water. while you are sitting you have a net force of zero because your body is not in moving up or down, but as soon as you stand up a force is applied in the downward direct

## The Physic of the Clean and Jerk (Kinematics)

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

## An Harmonica

The harmonica is by far my favorite instrument, I love the different types of music that can be played on it as well as the many different characters you find playing it. Recently I have been teaching myself how to play a harmonica and have been wondering the physics behind it. In each hole of the harmonica there lies a reed, all of which are different in size. When you breathe into the harp of the harmonica the reeds vibrate at different frequencies causing the different pitches you hear. Each

## Physics of Whistling

Almost everyone can whistle and people often do it when they are bored or are whistling along to a song, but how exactly do we whistle? Well, you can only make whistling sounds at the resonance frequencies of your mouth, because at the resonance frequencies the pressure changes due to the moving air. You can change the resonance frequencies by changing the position of your tongue. By moving your tongue up and down, and blowing harder or softer, you can change the pitch and amplitude of your whis

The Guillotine is a device used to cut off peoples heads. It was used very much ion the french revolution and hopefully isn't used at all today. While to guillotine is often seen as a machine of death, the mechanics and physics behind it is often underappreciated. The blade of the guillotine is brought up to the top of the device and tied down to hold it in place. When the object that is in need of some chopping is put into the restraints the rope holding the blade is cut and the blade, which is

## Physics of Tom Clancy's Rainbow Six Siege

Rainbow Six Siege is a popular first person shooter game that emphasis the use of destruction for tactical capabilities. With breakable walls, floors, windows and doors, destruction in the game is quite useful and very immersive. I remember a round in the map House where I was help up in the basement defending the hostage. I had reinforced the walls behind me with barriers that prevent the walls from being breached and put a c4 charge on the wall in front of me. I sat and waited to hear footstep

## An Physic C

This year in physics C I have learned many things. Many of which have expanded my knowledge in physics and as a person. I have learned much about myself. I now know that I wont be able to understand everything the first time, that I need to work hard to achieve the things that I want, and that Mr. Fullerton is for the boys. While I haven't been the best student this year, I can confidently say that Mr.Fullerton has taught me many skills that will stay with me for the rest of my life. From teachi

## Mr.President

During the recent inauguration of President Donald Trump, you can see bullet proof glass all around him. I got to wondering how exactly ballistic glass works. Bullet proof glass is made up of layers of glass and polycarbonate. The two materials are alternated and cannot not stop a bullet by themselves. A piece of glass by its self will shatter and a piece of polycarbonate by its self will be punctured. When the two are layered together, no bullet will get through. The bullet proof glass complete

## Squats Baby!!!!

Everyone seems to skip leg day, not me!!! Leg day is by far my favorite, especially back squats (I can back squat 365lbs ladies ). While the back squat is a simple movement, it requires tremendous power in your legs. To perform a back squat you must place the bar on the back of your shoulders, lower your hips down bellow parallel and bounce out of the bottom of the squat . Once you bounce you will reach a spot in the lift where you will have to push down on the ground in order to push yourself a

## The Snatch

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 hi

## The Hook Grip

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

## Curling

Ever wanted to know the physics of curling??? NO???? Well to bad im gonna tell you. Curling stones are made from thick granite stones, weighting about 20 kg, with a handle on top. The heavy mass of the stones makes it so it doesn't slow down early. The sweeping of the ice before the stone reaches that spot decreases the friction of the stone with the ice. The little bit of friction caused by the front of the stone melts the ice a tad and creates water which reduces the friction. By controlling t

## Physics of Swinging

Swings are found in children's playground and are very fun and enjoyable. They work just like a pendulum. A swing converts potential energy into kinetic energy as you swing. When you first get on the swing and take step back as far as you can to get the best swing you build up potential energy. When you pull your feet up and begin to swing your potential energy is converted into kinetic energy.  When you reach the the maximum height form swinging your potential energy is built up and again is lo

## Catch these Hands!!!!!

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 mu

## The Physics of Nothing

Take way everything in the universe and be left with nothing. Well except there can never really be nothing. At the zero-point energy, or the ground state of the Universe, isn't actually a state of zero energy. On the contrary, it's a finite, positive value not only that but a universe of nothing still has a size, a shape and it is still a physical object. The concept of nothing is very hard for scientist to understand because there is truly never nothing. By having nothing you actually have som

## Ouch! I Think I threw a disk!!

The Discus is a moment in which the thrower does some spin stuff and then launches the disk across a long distance. The discus has many factors in which effect the throw of it. The first being momentum. During the spinning part, momentum is built up and then the disk is released. In the air the disk cuts through the air because of its aerodynamic shape. Also the spin is a very important part of its flight. The faster its spins, the more stable it becomes. It is very important for it to remain st

## Its up.... and.. it is good!!!!!

During the Steelers fantastic win last Sunday over the Chiefs, The Steelers kicker Chris Boswell set the NFL record for most field goals in a postseason game. Hyped up on the win and excitement I got to thinking, What is the physics of kicking a field goal? So I went and looked around and found exactly what I was looking for. Kicking a Field Goal is a very complex thing believe it or not. You have to consider things such as wind, air resistance, and momentum. Momentum is a key factor in having m

## Sack that quarter back!!!!!!!

Tom Brady is an elite NFL QB, some argue he is the best ever! With the up coming AFC champion ship game; Patriots vs. Steelers, I was wondering just how much force is need to put Toms little self into the dirt. Tom stands at a solid 6 feet 4 inches and a hefty 225 lbs. Now to calculate Toms force we use the equation F=ma. F is the force, m is the mass, and a is the acceleration. Knowing Tom, all he is going to do is sit in the pocket and not move giving him an acceleration of 0 as well as a forc

## Size doesnt matter

Hey folks, breaking news, size doesn't matter. 100% of astrologists agree that a more massive planet doesn't necessarily have a larger gravitational force. Take Uranus for example, it very massive compared to us here on earth. In every way Uranus is larger than Earth, radius, mass, surface area, and volume. However because of earths smaller radius it has a larger gravitational force. The equation for gravitational force is F=G(M1M2/r2). The gravitational field on Uranus is 90% of that on earth.

## The Physics of stealing a cat

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 Am

## An Clockwork Physic

Integral to the operation of the mechanical watch is the balance wheel. Balance wheels are constructed of a weighted wheel and a spiraled torsion hairspring. The wheel is composed of a metal alloy with low thermal expansion, and the spring is made of either steel or silicon. Energy stored in the watch's mainspring is translated through the gear train to the escapement, a trident shaped piece with a dedicated escapement wheel which delivers impulses to the balance wheel. The balance wheel is what

## The Physics Besiege

Besiege is a physics based game where players build medieval siege engines to destroy their foes.  In the game you use things like springs, motors, wood blocks, and wheels to build almost anything you can imagine. Say you want to build a catapult to take down that castle in front of you, no problem. Before you begin launching projectiles out of the catapult, make sure it either has a counter weight or a suspension system to keep the catapult where it is. If you forgot to do this, the catapult wi

## GUNS! GUNS! GUNS!

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 incredi
