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 Snow - The most basic form of an ice crystal is a hexagonal prism. This form occurs because certain surfaces of the crystal, the growth facets, grow very slowly. The reason these facets exist derives from the molecular structure of water, and how water molecules arrange themselves into a crystalline lattice. The hexagonal prism includes two hexagonal "basal" faces and six rectangular "prism" faces. Note that the hexagonal prism can be "plate-like" or "column-like", if the length along the c-axis is short or long compared to the length along the a-axes....   [tags: physics snow] 2464 words

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

I have always been able to throw a decent curve ball; you don’t just throw 6 one hit games in your high school career without one. I have always wondered why and how the ball curves through the air, and it wasn’t until now that I have really had the chance to research a topic that has puzzled me for so long. I would bet that even pitchers in the “Big show” don’t know how or why, but they obviously have the talent and ability....   [tags: Physics Research Papers] 800 words

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

The Mirrors of Classic Physics - The Mirrors of Classic Physics Plenty of conceptions of mirrors are not so different from models in middle school physics. The mirror is a line dividing the ‘real’ from the ‘virtual’, and the image is the same on both sides. It is a plane in three-dimensional space, a slash in textual space, and a boundary to fluid spaces. In physics class, rays of light go from each point of the image and bounce off the mirror in such a way that they seem to have come from the virtual object. These are not the only mirrors....   [tags: Physics Science Self Identification Essays]
