Acceleration Definition

srashley216 — 2015-04-06 17:31:34 UTC

Acceleration: the rate at which the direction or speed of an object. Acceleration makes roller coasters go faster.

Centripetal Force and Centrifugal Force Definitions

srashley216 — 2015-04-09 04:27:44 UTC

Centripetal Force: forces motion to move in an inward direction. This force is what makes motion move inwardly through a circle.

Centrifugal Force: The force that pulls motion in an outward direction. This force is caused by inertia.

Both Centripetal force and Centrifugal force are what make roller coasters able to do loop - the - loops.

g Definition

srashley216 — 2015-04-09 04:43:00 UTC

g: A unit that measures acceleration equal to the acceleration caused by gravity. When people are building roller coasters, they use g's to make sure that roller coaster isn't to fast or too slow when people go on it.

Momentum Definition

srashley216 — 2015-04-09 04:48:39 UTC

Momentum: Depends on the mass and velocity of the object. Momentum is used in roller coasters like California Screamin' at California Adventure to get the ride started at high speeds

Weightlessness Definition

srashley216 — 2015-04-09 04:53:16 UTC

Weightlessness: A sensation (not an actual change in weight) that people experience often on roller
coasters like Tower Terror at California Adventure because their seat feels as if it has dropped out from under them.

What is Friction? How does friction relate with roller coasters?

srashley216 — 2015-04-09 05:05:58 UTC

Friction is the force that resists the motion of an object. Friction is used when roller coasters use brakes to slow down and stop at the end of the ride.

Potential Energy

srashley216 — 2015-04-09 05:58:15 UTC

Potential energy is the energy of an object depending on its height above the ground. An example of this is when Bill Nye took the bowling ball attached to the string and lifted it up higher before dropping it. Lifting the bowling ball up even more gave it more potential energy. the bowling ball had the most potential energy when BIll Nye was pulling it up and the least when he dropped it Potential energy is measured in Joules (1 Joule = 1 kgm2/s2). The equation for potential energy is PE=mh(9.8m/s/s).

Kinetic Energy

srashley216 — 2015-04-09 06:09:56 UTC

Kinetic energy is the energy an object has depending on its motion. The faster something is moving, the more kinetic energy it has. Kinetic Energy is measured in Joules (1 Joule = 1 kgm2/s2). The kinetic energy equation is K=1/2mv2

Our Group's Roller Coaster Design

srashley216 — 2015-04-10 19:05:36 UTC

On our roller coaster, we included a drop, a clothoid loop, and a couple of hills. At the end we had the marble jump into the bucket.

The Average speed of our marble was 2.07 m/s

The potential energy was 11.4 g

How do Kinetic Energy and Potential Energy change throughout a roller coaster ride?

srashley216 — 2015-04-13 17:16:41 UTC

When the roller coaster car is going up a hill and getting ready to go down the hill, the potential energy is building. The car has most potential energy at the very top of the hill. Then, the potential energy changes into kinetic energy. As the car goes down the hill it speeds up. The more it speeds up, the more kinetic energy the car has. So the potential and kinetic energy change as the car goes up and down the hills and loops.

The History of Roller Coasters

srashley216 — 2015-04-14 05:20:59 UTC

Roller Coasters have been around for a long time. But have you ever wondered where it all began? Here is some information on the history of roller coasters:

The first roller coaster was built in the 17th century near Saint Petersburg, Russia. In fact, the first roller coaster wasn't even a "real" coaster, it was an "ice slide." the slides were built to a height of between 70 feet (21 m) and 80 feet (24 m), consisted of a 50 degree drop, and were reinforced by wooden supports.

The first loop was built in Paris from an English design in 1846, with a single-rider wheeled sled running through a 13-foot (4 m) diameter vertical loop. These loop designs were called "Centrifugal Railways."

In 1959, Disneyland became home of the first steel roller coaster, "The Matterhorn Bobsleds." Steel roller coasters became known as the modern roller coasters.

Now you know a little bit more about the roller coaster's ride through history!

How does a Roller Coaster continue to move through twists and turns of the ride if it only uses an engine at the very beginning?

srashley216 — 2015-04-14 07:27:13 UTC

It's all based on kinetic and potential energy. Like I was saying before, potential energy and kinetic energy are constantly rising and falling as the coaster goes up and down. This causes energy conservation to happen. Every time the coaster goes up, more potential energy is being made and saved up. As the coaster goes down, the potential energy is turned into kinetic energy. The boost at the very beginning from the engine gives the coaster a lot of potential energy to start with, then every time the coaster goes up, it stores up even more potential energy, so it never runs out. That's how it only uses the engine at the VERY beginning
