The physics of making a pizza

Over the past year and a half I've watched the pizza makers at Cam's, and even made a few myself, and never even realized how physics can apply to my job. While stretching the pizza dough (the part that everyone loves....throwing the dough in the air!) the pizza maker throws the dough up and catches it again, stretching the dough out to make it however big it needs to be. This involved vertical motion because the pizza maker throws the dough up with a certain velocity and the force of gravity pu

Physics in the Military

Physics is very important in the air force because if you need to bomb a particular place, or drop any sort of packages to a certain place, you need to know when it would be best for you to drop whatever it is that you need to drop. whoever is dropping the package is going to need to know the velocity, angle and know the accelerations in the vertical and horizontal directions. Using this information, the people can figure out how long it's going to take for the package to hit the ground. Using t

Physics of soccer

When I played soccer I never realized how much physics there was. For example, if I want the ball to go its maximum distance, I should kick it at 45 degree angle. Also, There is horizontal and vertical motion involved, all while I'm moving! As I'm running, I would apply force to the ball, causing mainly horizontal motion. However, if the ball came off the ground, vertical motion would now be involved and the force of gravity competes with the time the ball is in the air before gravity pulls it d

Physics of Singing

As I was listening to Kristen sing in the car, I was thinking about the physics in her making the noise and me hearing it. As she was creating this noise, the sound waves had to travel through a medium, being air molecules. As the wave moved through the air it vibrated them, creating the noise. As this happened, the air molecules hit my ears. I could also figure out how long it would take for me to hear Kristen singing by using velocity=distance/time. Velocity for the speed of sound is 331 m/s a

Momentum and impulse in the car

When you get in an accident in your car, have you ever wondered why the airbag goes off? This is to keep to more safe. As newtons stated, an object in motion will remain in motion until acted upon by an outside force. If you didn't have an airbag that outside force would either be the steering wheel or the windshield and both of those would hurt pretty bad. So what the airbag does is it allows for more time for you to stop completely. You hit the airbag and the resistance allows you to slow down

Physics of Ice Hockey

Until I took physics, I never thought that there could be science involved. I used to just watch my brother and all of his friends play hockey and think it was so cool how with a little bit of force, they could hit a puck so far. There is physics in ice hockey in many different forms. For example, if one of the players hits the puck, the puck automatically has a velocity, depending on how hard he hit it, and follows a parabolic shape if it comes off the ice until it hits the ice again. When the

How Traffic Investigators Use Momentum

There are many ways investigator's can use physics to figure out what happened in a crime scene or an accident but one way is by using momentum. By using momentum they can figure out how fast the car was going to determine if that person really stopped at the red light or stop sign. This is possible because if somebody didn't stop at a stop sign and T-boned another car you would be able to figure out that they never stopped because the accident would be greater. The momentum in the car would be

The Physics of a Trampoline

We've all had those moments as a child where our parents tell us not to do something and we do it anyways. My mom never wanted me or my brother on a trampoline until my dad came home with one and she didn't have a choice but to let us jump! Come on---What's not irresistible about built up potential energy in springs shooting you upward and then you making a (semi) safe landing space as the springs fill back up with potential energy. The low spring constant in the trampoline springs sends you fly

Physics in Playing Tug-of-War

My crazy 100 pound german shepherd loves playing and when we fight over his toys we both exert forces on each other and as the toy moves between us we are both doing work. When me and Shiloh play tug of war with his toys, he usually wins. Due to the fact that I am pulling as hard as I can to get the toy out of Shiloh's mouth, when I win I have done work. However, it usually takes me a long time which means overall I use less power. If I were to use more power, the time would be shorter and Shilo

Introduction

Hi, I'm Shannon and I am a junior this year. I used to play soccer and softball until I hurt my hips and now am no longer able to play any sports at all. I work a lot at Cam's Pizzeria, either making pizzas or taking care of customers. I love my job there and have made many friends there. I really do enjoy school however my weakest point is test taking. No matter how hard I study, I never seem to do very well. I am hoping to find more effective ways of studying this year in hope of becoming a be

Reducing Sport Injuries

When playing any sport there is a lot of impact on the players bodies which can cause them to get hurt. During a hockey game you seem more checks than you can count but if hockey players knew what to do when they were about to get hit the number of injuries would reduce immensly. If a really big guy is coming at you, he's going to have a really big momentum when he hits you and that momentum will turn into impulse on you as soon as he hits you. To reduce this, considering you can't reduce how mu

Winters in Rochester

During the winter the roads here can get pretty bad. The roads can be covered with ice and slush making you slide when you turn or try to stop. The ice and your rubber tires together have a very low coefficient of friction meaning that when those two surfaces are moving (one on another) the amount of friction between them is very low. This is what causes your car to slide as you turn or when you try to stop. Plus, once you start sliding all frictional forces are acting against you, in the opposi

Christmas Lights

So, everyone knows the struggle of a string of Christmas lights going out and having to check every bulb until you can find the one single bulb that went out. This happens because Christmas lights are set up in a series circuit. This means that there is only one path for electrons to flow, so if one light goes out, there is no alternate path to get around the one that went out and to the other lights. Putting Christmas lights in a parallel circuit would be more beneficial to buyers because when

Physics in Music

As for many instruments resonance, or the vibrating due to an equal frequency, causes the sound. For an opera singer to break a glass with just his/her voice they would have to match the frequency or pitch that they sing at to that of the glass. When the opera singer hears the frequency of the glass, being trained they can match it to the sound that comes out of their mouth. This causes the glass to vibrate and eventually shatter once the pitch is perfectly met. For a guitar, the strings are wha
