ROLLER COASTER COMPONENTS
ROLLER COASTER
ROLLER COASTER
Roller coasters are driven almost entirely by basic inertial, gravitational and centripetal forces, all manipulated in the service of a great ride. Amusement parks keep upping the ante, building faster and more complex roller coasters, but the fundamental principles at work­ remain the same.

1. Friction: the act, effect, or an instance of rubbing one object against another

2. Gravity: the force of attraction that moves or tends to move bodies towards the center of a celestial body, such as the earth or moon

3. Acceleration: the act of accelerating; increase of speed or velocity.

4. Potential energy: system as a result of its position in an electric, magnetic, or gravitational field

5. Kinetic energy: the energy of a body or a system with respect to the motion of the
body or of the particles in the system.

6. Inertia: the property of matter by which it retains its state of rest or its velocity along a
straight line so an external force does not act upon long as it.

7. Force: strength or energy; might; power: the force of the blow; a gale of great force

8. Momentum: a quantity expressing the motion of a body or system, equal to the product of the mass of a body and its velocity, and for a system equal to the vector sum of the products of mass and velocity of each particle in the system.

The earliest ancestor modern roller coaster was made Russia on 16th and 17th centuries the roller coasters were monumental ice slides -- long, steep wooden¬ slides covered in ice, some as high as 70 feet. Riders shot down the slope in sleds made out of wood or blocks of ice, crash-landing in sand pile.

The first roller coaster was in the 1920s at coneys island.
Unlike a passenger train, a roller coaster has no engine or power source of its own. The first energy that’s slowly increases is motor energy when it goes up its first hill. The mechanism is not need for the second hill because the momentum from the first down hill pushes it bake up.
Roller coasters need chain doges because once the chain dogs are working they pull the train to the top of the hill.

The roles of potential and kinetic energy differ between the newer catapult- launched coasters and the older style of roller coasters because the gear at the bottom and top of the train help the chain loop go around .
Gravity and potential energy work together to give you a great ride on a roller coaster because potential energy and gravity together to create moment which pushes the roller coaster down the other side and then up again.

Potential energy can become kinetic energy during your ride because the potential energy that builds up going up the roller coaster is released as kinetic energy.

The role of tracks on a coaster control the way the coaster cars fall.The tracks and gravity work together to insure that you have a sweet ride on the coaster by gravity applieing constant downwards force on to the cars.

Newton’s First Law play in the explanation of why a roller coaster is able to keep moving even though it does not have a motor powering it this is because the coaster car will maintain a forward velocity even when its moving up the track, opposite the force of gravity.
