Miles Per Second Speed Of Light
1,615 wordsOur universe is a vast abyss, always expanding without bound. Many objects in space are exciting and intriguing. Mysterious surround many findings and cosmologists, astrophysicists, and astronomers work to obtain a better understanding of these strange phenomena. One great mystery is that of the black hole, which since the early 1960? s has been the object of many scientists? work, but has been dated to be the topic of discussion since 1783, when a astronomer named John Michell first recorded hi...

Special Theory Of Relativity Force Of Gravity
454 wordsAccording to Einstein's Special Theory of Relativity, light can be bent. This is a concept that seems to contradict the well-known law that states that all light travels in a straight line. But they do not contradict each other. Light does travel in a straight line; only the space-time continuum bends around it causing it to change direction. This bend or warp in the space-time continuum is a result of the presence of mass, also known as gravity. Gravity is a force that is always present, always...

Eccentric And Concentric Muscle Contractions
1,323 wordsIso kinetic, Eccentric, and Concentric Muscle Contractions There are three basic types of muscle contraction: isometric, isotonic, and iso kinetic. An isometric contraction occurs when a muscle contracts, producing force without changing the length of muscle. To demonstrate this action, in the sitting position place your right hand under your thigh and place your left hand on your right biceps muscle. Now, pull up with your right hand or in other words, attempt to flex your right elbow. Note tha...

Center Of Gravity Sun Tzu
1,510 wordsClausewitz advocates attacking enemy schwerpunkt or centers of gravity. How does this compare with Sun Tzu's prioritization for attacking important elements of national power? Which theorist provides the most useful guidance for determining the object of a strategy or strategies? Introduction Clausewitz's attack of enemy centers of gravity and Sun Tzu's prioritization of attack of important elements of national power provide contrasting approaches to the development of effective strategy. These ...

Tennis Ball Centrifugal Force
3,996 wordsThe tennis serve is the stroke that puts the ball in play and is often referred to as the most important stroke in the game of tennis. It has become a principle weapon of attack and is used to place the opponent on the defensive by forcing a return from the weak side or by moving the receiver out of position. A good strong serve can sometimes be the basis of winning a game of tennis. I have included eight picture sequences to illustrate the tennis serve. Represented in picture A is the stance of...

Billions Of Dollars Time And Effort
3,117 wordsThe International Space Station The International Space Station is the doorway to the future of mankind and the world as it is known. The scientific and medical discoveries that will be made on the station could create billions of dollars annually. A plan like this, arranged to benefit the whole world economy, should sound like a good idea to every person, but some believe that the ISS is too risky, too ineffective, or too costly to create. Whether or not the space station is worth the money, ti...

Sir Isaac Newton Robert Hooke
2,697 wordsAs a young boy at King s School in Grantham, England, Isaac Newton was a poor student. His test scores were well below average and were near the bottom of his class. One day as he walked to school a boy academically above him insulted and kicked Isaac. This made Isaac angry, so he challenged this boy to a fight after school. Newton easily won the fight that afternoon, but that was not enough. He had to do something better to avenge himself. He decided he would beat the boy academically as well. ...

Big Bang Theory Hydrogen Ions
3,468 wordsLuminosity is the amount of light that is radiated from a star. White light is the composition of all colors. In elements, the energy discharge can be displayed as light. Just by looking at the colors that are discharged, one may precisely identify the element. In understanding the universe, the Doppler effect is one of the most important tools. The Doppler effect is a shift in frequency due to a moving source. Skipping a rock on water would be an example of this effect. The circles would be off...

Force Of Gravity Roller Coaster
1,477 wordsIndividuals love to go to the amusement parks and try out the rides that are available. The most common and thrilling ride is the roller coaster. An amusement park is not an amusement park if it does not contain a roller coaster. What makes these roller coasters so fun that every amuse parks has one. A lot of people would say it is their extreme high speeds that makes it very exciting. That is a valid answer, but it is the wrong answer. The speed has nothing to do with the excitement. It is more...

Big Bang Theory 20 Th Century
3,306 wordsAlbert Einsteins theory Relativity Relativity Albert Einsteins theory of relativity has caused major revolutions in physics and astronomy during the 20 th century. It introduced to science the concept of relativity the notion that there is no absolute motion in the universe, only relative motion thus superseding the 200 -year-old theory of mechanics of Isaac Newton. Einstein showed that we reside not in the flat, Euclidean space and uniform, absolute time of everyday experience, but in another e...

Speed Of Light General Theory Of Relativity
3,151 wordsI. Introduction 1. Theory of Black Holes Black holes are one of the least understood phenomenons in the galaxy yet the secrets contained within the black hole could revolutionize the field of physics. Black holes are formed when an enormously massive star, most likely a neutron star, collapses in on itself. This happens because when the star dies all the energy generated from the sun s fusion reaction that was formerly pushing outward suddenly stops. When the outward force stops, the sun has so ...

Theory Of Relativity Black Hole
1,924 wordsWith all the excitement surrounding the new Star Wars movie, it is a big day for lovers of science fiction. But how much does the average person really understand about beaming up; phaser's and photons; wormholes and warp drive? How powerful are these fantasies compared to the real thing? If theories of their existence are true, black holes are the most powerful force in the known physical universe; however, do they even exist? Most scientists believe so, but by their very nature, black holes ar...

M P H Black Hole
3,742 wordsBlack holes are objects so dense that not even light can escape their gravity, and since nothing can travel faster than light, nothing can escape from inside a black hole. Loosely speaking, a black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull. Since our best theory of gravity at the moment is Einsteins general theory of relativity, we have to delve into some results of this theory to understand black ...
