Physics of the Lathe - "How much wood could a woodchuck chuck if a wood chuck could chuck wood?" An age old tongue twister that has never been answered. In this rhyme, the common assumption is that the woodchuck is a small furry groundhog like creature, but there is another kind of wood chuck that is not as common but could chuck wood. Here we will explore this path of answering this age old riddle. In the production of many wood products a common manufacturing tool known as a lathe is used, and to hold the wood in the lathe a chuck is used....   [tags: physics lathe wood] 681 words

Physics of the Eyes - Protections of the eye: The human eye is one of the most important things to a person and thus has many forms of protection. The eyelid protects the eye in three different ways: the eyelashes, the glands, and the movement of the eyelids. The eyelashes are beneficial in keeping dust and debris out of the eye. Touching the lashes will trigger the reflexive blinking mechanism. There are many different glands that are located in the eye. The Zeis gland is a gland that secretes oil. An infection in this gland results in a stye....   [tags: physics eye sight]

The Physics of Baseball - Swinging the Bat for Power Many people might think that swinging the bat straight through the ball would be enough to hit the ball a decent distance off the bat. There's many more mechanics involved in the swinging process. Muscle has only a small part to play in the swinging a bat for power. There are two types of mechanics involved while swinging a bat, Linear and Rotational. Rotational mechanics are the dominant source of power in the swing. Out of the rotational mechanics come the two forces that help generate the speed and power of the swing, torque and the other comes from the energy of rotation....   [tags: Sport Baseball Physics] 1526 words

Physics of the Moon - Gravitational Force of Bodies All bodies with mass exert a gravitational pull on the bodies around them, even you and me. The larger the radius and mass of the body the larger the force. Most people know that the force of gravity on earth is much greater than on the moon, but how much larger is it, and how is gravity calculated. German astronomer Johannes Kepler (1576-1630) spent years observing the motion of planets and developed a set of laws for planetary motion. Years after his death Physicist Isaac Newton (1642-1727) used these laws to help him develop his law of universal gravitation....   [tags: physics science space] 831 words

Physics of Submarines - Submarines have been around for longer than most people think. The first American attempts at creating a submersible boat date back to the days of the Revolutionary and Civil Wars. These boats, however, turned out to be just as dangerous to the people on board as they were to the enemy boats. So the concept was put aside for a while. But in the 1890's two men named John Holland and Simon Lake built a practical underwater boat. The US Navy bought its first submarine from Mr. Holland on April 11, 1900, a date which is thought of as the birthday of the US submarine force....   [tags: physics submarine] 2121 words

Physics of Skydiving - Acceleration..... Galileo demonstrated that an object falling only under the influence of gravity will experience a constant acceleration, i.e.., it gains the same amount of velocity for every additional second that it falls. (5) On earth this amounts to 32.14 ft/sec/sec, meaning that it increases its downward velocity by 32.14 ft/sec for each second that it falls. If acceleration is constant, then it follows that the downward velocity V an object experiences at any time t after the start of the fall is given by: V=g t where V=velocity (m/sec) t=time (sec) g=acceleration due to gravity One can also show that the distance d fallen after time t is: d= 1/2 gt^2...   [tags: physics skydive] 633 words

The Physics of Music - ... As the sound is propagated outward, it is “spread” over a greater area. The minimum sound intensity that can be detected by the human ear (called the threshold of hearing) is about 10-2 W/m2. At a greater intensity of about 1W/m2, sound becomes painful to the ear. The frequency of a sound wave, seeming as pitch, is the number of compressions (or rarefactions) that pass a fixed point per unit time. The frequencies audible to the human ear range from approximately 20 hertz to 20 kilohertz. Intensity is the average flow of energy per unit time through a given area of the medium and is related to loudness, (Shipman-Wilson-Higgins, 2013)....   [tags: frequency, pitch, waves] 876 words

Physics of Stopping a Bike - In short brakes are a tool that turn kinetic energy into heat(http://en.wikipedia.org/wiki/Brakes). This is accomplished by applying friction in one way or another. In the case of disk brakes friction is created because the braking mechanism exerts a force on the break pads which pushes them into contact with disk. It is this contact combined with the fact that the disks are rotating that causes kinetic energy to be converted to heat. If the purpose of brakes is to convert kinetic energy into heat, then in order to know how much heat the brakes make requires that we find out how much kinetic energy there is in a moving bicycle....   [tags: physics bicycle] 1355 words

The Physics of Cooling Techniques - There are many reasons for wanting to cool things, but whatever the reason, the Second Law of Thermodynamics dictates that cooling something will take effort (sorry, no spontaneously cool sodas). Different techniques have been developed to address this issue, each having its own limitations and ideal uses. The most commonly used method of cooling is with vapor-compression cycles, because it is fairly easy to construct a cooling device employing this method and the cost is low. In fact, conventional refrigerators use this method of cooling to keep your leftovers and drinks chilled....   [tags: thermodynamics physics refrigerator] 2370 words

The Physics of Motorcycle Roadracing - Despite what some people may think, motorcycle roadracing is not only a highly strenuous sport, but there is much more involved than just twisting the throttle and turning the handlebars. There are a number of powerful forces working on the bike and the rider. There is, of course, the downward pull of gravity, friction between the tires and the track, and centrifugal force which acts to the outside of the turn. The key to cornering at high speeds is to perfect the lean angle of the motorcycle so that the force of gravity reaches equilibrium with the centrifugal force attempting to stand the bike back up....   [tags: physics sport sports motorcycle] 971 words

Physics of Tennis Racquets - Missing figures Tennis racquets with old type of strings did not allow power and control over the racquet at the same time. To get a powerful stroke player had to hit the ball with the area of racquet closer to the tip of the racquet (toe). To obtain control and to reduce vibration of the racquet, player had to hit the ball with the area of racquet called “sweet spot”, located around the geometric center of the head. NASA’s 1973 Skylab 3 mission showed that tapered strings can move the “sweet spot” from the center of the racquet toward the position of greater power....   [tags: physics sport sports tennis] 830 words

A common misconception is that the car in front of us throws rocks "backward" and hits the following car's windshield. A rolling tire cannot throw a rock backwards. A tire is a rolling object, thus every point along the tire is moving forwards. There is no force going in a backwards direction. Only direction part of a rolling object can go is a combination of up or down, and forward. The velocity of the rock at any given point can be determined by adding it's translational velocity at the center of mass (the orange arrow) with it's rotational velocity....   [tags: physics tire rock] 419 words
