Physics Final Exam - 1. A wavelength is the distance from the peak of a wave to the next peak. The frequency is how often the particles of a wave vibrate. Because the wavelength is a distance, and frequency is a time, when they are multiplied, the velocity of the wave must be found. An example of this relation is a slinky. When the waves are more separated and it takes less time for the wave to vibrates, the slinky is clearly moving more quickly. 2.Transverse waves are waves that have particles moving perpendicular to the wave motion, while longitudinal waves have particles that move parallel....   [tags: Physics] 718 words

Physics of Soccer - Physics of the Ball How and where you kick the ball is the most important aspect within the game of soccer. Lets say you kick the ball perfectly giving it no rotation (or spin), this means that you have given the ball a velocity (v) and an initial angular speed of zero. When the ball comes into contact with the ground it will begin to spin because the ground is not frictionless. The soccer ball will eventually begin to roll without slipping, which is when the balls center of mass is equal to its angular speed....   [tags: physics sport sports soccer football] 1400 words

Physics of Meteors - A falling star is really a Meteor and is a form of space debris. They are not really stars at all. There are cases where meteors have entered the Earth’s atmosphere. In most cases, Meteors burn up upon entry into the atmosphere and never make it to the surface of the planet. There are times when the meteor starts to burn up, but because the mass is big enough, it makes it to the surface, smaller then when it started out. Through both means, the meteor deals with some measure of resistance upon entering the atmosphere....   [tags: physics space meteor falling star] 586 words

There are many forces that act on a sailing ship to put it in motion, but the buoyant force is what is required to keep the boat from sinking. A buoyant force is the normal force that pushes up on the boat supporting its weight in a fluid. The buoyant force "equals the weight of the fluid displaced by the object."(pg.427, Serway and Jewett) This concept is Archimede's Principle....   [tags: physics sail boat sailing boating]

Framework and Physics of an Autogyro - To fully understand the physics of an autogyro, one must know what it is. An autogyro is an aircraft, similar to a modern helicopter in appearance, but with a few major dissimilarities. It, like a helicopter, uses an overhead rotor as its main source of lift. The rotor on an autogyro, however, is freely rotating, meaning it is not powered by any engine, and therefore applies no rotational force, or torque, on the machine. This nullifies the need for a tail rotor like that of a helicopter's because there is no need to stabilize the fuselage from twisting....   [tags: Physics Science Helicopter Aircraft] 2622 words

The Physics of Turbo Charging - The Physics of Turbo Charging Turbo charging is one of the most efficient ways to make an engine preform better. They are very common on cars with smaller displacement engines and are even showing up on cars as a production item these days. As common as they are though, very few people truly know and why they work. They are fascinating even though they are fairly simple, or at least the principal behind them is simple. To under stand how and why a turbo charger works one must first understand how the modern automobile engine works....   [tags: Turbo Charging Engines Physics Essays]

Physics of Cross Country Skiing - Cross Country Skiing has existed since prehistoric times. The oldest pair of skis were found to be over 4500 years old. Skiing was used as a way to travel or hunt during the winter season. The skis were designed not so much for speed but to keep the skier on top of the snow. Traditionally, the skis were made of wood, the poles were made of bamboo with leather hand straps. The boots were also made of tough leather and were fastened to the skis with sinew made from animal hides. Skiing was believed to have originated from the Scandinavian countries and this fact is complimented by active skiing lifestyle that we see today....   [tags: physics sport sports ski skiing] 1312 words

Physics of Paper Airplanes - Paper Airplanes, flight at its simplest for humans. As kids, we learned how to build paper airplanes and send them soaring into the sky. We didn't stop to think about why the airplanes where able to fly after the initial thrust we gave them or how they were able to glide for so long afterwards. Ignorance was bliss then, but now we strive to understand how things work. Looking back to the childhood past time of flying paper airplanes, I will try to explain some of the parts that make paper airplanes fly....   [tags: Physics Science Planes Plane Airplane] 1482 words
