Acceleration

Tmansd18 — 2014-04-08 20:32:52 UTC

Acceleration is when and object changes speed and also directions. So when the roller coaster cart is going down the gigantic drop, the acceleration will increase and it's changing direction by going down.

Centripetal force

Tmansd18 — 2014-04-08 20:40:46 UTC

Centripetal force is when a force is pushing an object inwards. So when your on the roller coaster and about to do a loop the force of the track is pushing on the cart, pushing the riders towards the middle or center

Centrifugal force

Tmansd18 — 2014-04-08 20:48:34 UTC

Centrifugal force is when a object pushes outward instead of the object being pulled in. So the cart of the roller coaster is pushing outwards on the track.

G's

Tmansd18 — 2014-04-08 20:58:46 UTC

G's or G-force is the amount of acceleration equal to the amount of acceleration due to gravity. It happens when a falling object changes it's speed and also it's direction. So on a roller coaster when you going through a cork-screw you are gaining G's because your changing your speed and changing direction.

Momentum

Tmansd18 — 2014-04-08 21:04:32 UTC

Momentum is where anything with mass that is in motion has a momentum. Actually the amount of momentum depends on the amount of velocity and also mass. So when on a roller coaster and you going down a giant drop, the mass of the cart and the velocity your traveling at determines how much momentum you will have.

Weightless

Tmansd18 — 2014-04-09 02:02:03 UTC

Weightless is when a rider or person does not feel the external force upon their body causing them to almost feel weightless. Say a 150 pound person is on a roller coaster and they are about to go down the drop of the coaster. They feel 150 pounds of external force from the seat. But once they go down the drop the seat go from under them so there is no external force on their body making them feel weightless.

Friction

Tmansd18 — 2014-04-09 02:08:54 UTC

Friction is a force that resists motion, almost trying to stop any possible motion. When two surfaces slide across each other, it creates a close interactions resulting in friction. Friction relates in roller coaster when the coaster is coming to a stop, it brakes slide on the tracks causing friction that helps the coaster stop.

Potential energy

Tmansd18 — 2014-04-09 02:36:41 UTC

Potential energy is energy that hasn't happened and is waiting to happen. Once the potential energy happens it then is converted to kinetic energy. Energy stored up on the forces acting on it. Potential Energy= Mass x g x height. So PE= mh (9.8 m/s/s). The least amount of Pe is when it goes downhill or is stopped.

Kinetic energy

Tmansd18 — 2014-04-09 02:42:26 UTC

Kinetic energy is the energy of motion. This means that the molecules are always moving. Kinetic energy will never have more energy than potential energy because the total amount of kinetic energy is how much potential energy is there. The amount. The mass + speed creates work, and movement equals energy witch helps create kinetic energy. Kinetic energy = 1/2 x mass x velocity^2, so KE or kinetic energy = 1/2mv^2. The least amount of KE is when it goes uphill or is stopped.

Joules

Tmansd18 — 2014-04-09 03:19:56 UTC

The unit of energy Is measured in joules. A joule is equal to the work done by force of a newton pointing to the direction of the force. 1 joule= 1 x kg m^2 divided by s^2.

KE and PE on a roller coaster

Tmansd18 — 2014-04-09 03:32:48 UTC

Kinetic energy and potential energy happens on roller coasters. The potential energy on a roller coaster is when your going up about to go down a steep drop. The potential energy part is going up when all forces stack up until you finally reach the top. When your going down is where the kinetic energy takes place. Kinetic energy happens when your going down because the work creates the energy and then movement happens causing you to go down the drop.

History of the Roller Coaster

Tmansd18 — 2014-04-09 17:52:58 UTC

The oldest roller coaster was from russia. The roller coaster was built in the 17th century built with a height of 70-80ft high and a drop of 50ft. These drops where supported by wooden panels. Historians believe that the first roller coaster was built by the French and not by the Russians.

Cool Roller Coaster Statistics

Tmansd18 — 2014-04-09 19:29:45 UTC

The tallest roller coaster is Kingda Ka, which has the height of 468ft. The fastest roller coaster is the formula Rossa with a crazy speed of 149mph. The roller coaster with the most loops is the smiler with a total of 14 loops! The biggest vertical drop is also Kingda Ka with a 418ft vertical drop. Finally the longest roller coaster is the Steel Dragon 2000 which is 8133.2ft long!

Bat Wings

This is what a batwing roller coaster looks like

Corkscrew

This is what a corkscrew looks like on a roller coaster

Step H major question

Tmansd18 — 2014-04-11 17:05:04 UTC

The first hill is the biggest factor, the hill of the coaster has all of the PE. This hill is the highest point of the entire ride so it gains a ton of potential energy. Once it reaches the top all of that PE that has been gaining is released into kinetic energy that helps the coaster until the end. So since the ride gains so much energy and speed, it's unnecessary to have an engine for the entire ride.

The scooper coaster

Tmansd18 — 2014-04-11 17:30:09 UTC

For our coaster the length was 7.4m, the average speed of our coaster was 4.1mps^2. The amount of potential energy was 0.53 joules, and the amount of kinetic energy was 0.05 joules.
