<center><h2>Usage of Physics and Velocity in Roller Coasters</h2></center>
<hr>
<p>Roller Coasters have been around for centuries giving people a scream for their money.
 It has always been a good example of speed, centripetal force, velocity, friction and distance. Roller coasters take you through an adventure of terrior with some coasters riding through loops and some riding over loops.  You can ride
not only sitting but standing up. There are also some where you can ride swinging and glinding on an over head track with a suspended roller coaster.  Also you can ride going backwards, free falling towards the earth at great acceleration.

Gardens Tampa, Florida.</p>


<p>Let's find out the physics used in these monstrous scream machines and take a look at how the cars can stay on the track while traveling through loops and twists.  But first I'm going to share with you some of the history of roller coasters.  The Russians were the one's who invented the roller coaster.  They built some icy slides that you got in this car and rode down sleding really fast and at the bottom their was sand that stopped you.  Then the Russians built the first coaster with wheels in 1784 but had some problems with them coming off when the riders went on them.  Then in 1804 the French made one with wheels too and called them roller coasters, but they too had difficulty with the wheels coming off.</p>

<p>Roller coasters use centripetal force in taking passengers into loops.  The cars are pushing down on the track while you are forcing up on the track so you are pressed together which is Newtons 3rd law action and reaction.  Once a roller coaster has gone down the first steepiest hill it can never goes as high again because of friction.  When you come over the first hill, the cars have to relie on it's own 
momentum to coast to the end of the ride.</p>
