Computer Simulations of Physics - Computer simulations are used very much in physics. Simple ones are used to do demonstrations of basic mechanics problems that would not normally be possible. Complex ones are used to simulate problems involving fluids, plasma, and turbulence. Some of these simulations are so complicated that entire installations are dedicated to them. There are many different applications of physics simulations. Almost all things in physics can be demonstrated. However, many of these things are much more fesable to simulate rather than to a physical demosntration....   [tags: Physics, Computers, Applications, Technologies] 318 words

Physics of Billiards - Physics can be found anytime, anywhere. Billards is one game where the more you know about physics the better a player you will be. Some of the main physics principles in Billards are: Newton's Laws: 1st: An object in motion tends to stay in motion while an object at rest will stay at rest, unless acted upon by an outside force. 2nd: Force is proportional to mass times the acceleration. 3rd: For every action, there is an equal and opposite reaction. Conservation of Momentum: In an isolated system, (a system with no outside force acting upon it) then the total momentum will remain constant....   [tags: physics sport sports pool billiards] 382 words

Physics of Billiards - The Physics of Billiards Newton's Laws First Law: An object at rest stays at rest. If it is moving, the object will continue to move with the same velocity. Second Law: The net force on an object is equal to the product of the objects mass and its acceleration. (F = ma) Once the cue ball begins to roll there are no net external forces acting in the two-ball system; therefore the a must be = 0. Acceleration is the rate of change of velocity. If acceleration is 0 there is no change in velocity. When the two balls collide the only forces acting are internal and they do not affect the net force....   [tags: physics pool billiards] 392 words

Physics of Baseball - Finding and understanding the sweet spot on a wooden bat. When you strike a bat against a ball it sends vibrations, much like the vibrations acting on airplanes or bridges, which travel in waves through the bat. This motion is important to understand because every vibration the bat experiences takes energy away from the ball's speed as it leaves the bat. If you hit the ball at a bat's "nodes", the frequencies (each bat vibrates at several low and high frequencies at once, which is like the harmonics of stringed instruments) cancel out and since this happens you don't feel the sting in your hands that you experience when you hit the ball at different points on the bat....   [tags: physics sport sports baseball] 630 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

Physics of Beer - Carbonated beverages contain dissolved carbon-dioxide gas. The way to get gas to dissolve in liquid is to pressurize the mixture, meaning that the pressure inside a beer can is greater than the pressure outside the can. This is why you see little bubbles spray out when you open a beer can. Breaking the seal depressurizes the mixture, causing the gas to come out of solution, starting with the gas closest to the top (that's where the pressure decrease starts). Because gas is lighter than liquid, as soon as it comes out of solution, it rises to escape the can....   [tags: physics alcohol beverage] 661 words

The Physics of Roller Coasters - A roller coaster is a thrill ride found in amusement and theme parks. Their history dates back to the 16th century. It all started in Russia, with long, steep wooden slides covered in ice. The idea then traveled to France. Since the warmer climate melted the ice, waxed slides were created instead, eventually adding wheels to the system. The first roller coaster in which the train was attached to the track was in France in 1817, the Russess a Belleville. The first attempt at a loop-the loop was also made in France in the 1850s....   [tags: Physics] 866 words

Physics of Music - "He who understands nothing but chemistry does not truly understand chemistry either" Georg Christoph Lichtenberg (1742-1799) Music is not purely a form of art. There is a great deal of science that goes behind the production of beautiful musical sounds. In order to understand how music is possible, one must have an understanding of physics. Physics allows us to create musical instruments with different tone qualities and the ability to be played in a certain way to produce a specific pitch or note....   [tags: physics music sound] 866 words

If gymnasts were physicists (or at least knew more about physics) they would be better equipped to handle the difficult aspects of gymnastics. As a gymnast I learned the motions that were necessary to complete the tricks that I was working on, and as a coach I taught others the same.

Most of the time this disturbance is by an earthquake but can be from meteorites, landslides, or even explosions. They are sometimes known as tidal waves but this is a misnomer because tsunamis have nothing to do with tides. While tsunamis are feared particularly in light of the December 26th tsunami, the physics behind them is fascinating. One the largest tsunamis in recent history was the Cascadia tsunami in 1700.

Physics of Black Holes - What are Black Holes. A black hole is theorized to be a collection of collapsed matter of whose gravitational pull is so strong that not even light can escape its force. The matter is is forced in a very, very tiny area and therefore the matter is very dense. Since light cannot escape, they are considered to be truly black. This, obviously, makes it hard to detect an actual black hole, and therefore, have only been theorizd to exist. These theories are slowly turning into "conclusive evidence." This evidence includes the particle dust given off from matter entering the black hole, as well as observations of orbits of bodies near the black hole....   [tags: physics science space] 1007 words
