Information on how physics works

Acceleration

bigbisquet2 — 2014-04-09 18:08:18 UTC

Acceleration is process were an object Changes it's speed or direction. In a coaster it would have acceleration when the coaster starts speeding up when going down a slope and or a turn.

Centifugal force

bigbisquet2 — 2014-04-10 01:11:32 UTC

A centrifugal force is a force that draws a rotating Body away from the center of its rotation. This force occurs in a coaster when it goes through a loop this is when the coaster is being forced to the tracks.

Centripetal

bigbisquet2 — 2014-04-10 01:14:23 UTC

Is a force that makes a something Follow a curved path. This occurs in a coaster when the gravity is reversed and the coaster is able to go upside down.

Momentum

bigbisquet2 — 2014-04-10 01:18:00 UTC

Momentum is the mass and velocity of an object. An example of this is a large truck that is heavy has a large momentum. The amount of momentum on a coaster depends on the weight and how much stuff is in the coaster.

Weightlessness

bigbisquet2 — 2014-04-10 01:22:28 UTC

Weightlessness is when there is no gravitational pull being acted on an object which is also called zero g. You feel weightlessness when their is a very steep and sudden drop.

Relation

bigbisquet2 — 2014-04-10 01:24:45 UTC

All of these words relate to rollercoasters because they all occur in most rollercoasters when you go over a loop or straight down or accelerate superfast

Friction

bigbisquet2 — 2014-04-10 01:27:46 UTC

Friction is when two objects rub against eachother and create heat. Friction relates to rollercoasters because the wheels on the rollercoaster are constantly rubbing against the tracks creating tremendous heat which will eventually make the rollercoaster stop

Kinetic energy

bigbisquet2 — 2014-04-10 01:36:19 UTC

Kinetic energy is when an object passes energy through into another object to make it move. Kinetice energy is the greatest when the coaster is going down a the steepest hill on the ride.

Potential energy

bigbisquet2 — 2014-04-10 01:43:43 UTC

Potential energy is when energy is stored in an object and just waiting to be released as kinetic energy. The highest point of potential energy is when the coaster goes up the largest hill in the ride and when the coaster reaches the top of that hill it has the max potential energy

Potential energy

bigbisquet2 — 2014-04-10 01:47:34 UTC

Mass x G x height = m h x 9.8 m/s/s

Kinetic energy

bigbisquet2 — 2014-04-10 02:02:02 UTC

Kinetic energy = 1/2 x mass x velocity squared = 1/2mv squared.

PE and KE changes

bigbisquet2 — 2014-04-10 02:07:03 UTC

PE and KE change throughout a rollercoaster ride because when the coaster is traveling up it gains PE and when it reaches the peak it starts using that stored PE and turns it into KE do go down.

The history of roller coasters

bigbisquet2 — 2014-04-11 17:09:22 UTC

The oldest roller coasters descended from the Russian mountains which were specially constructed of hills and ice and all this was located around saint petalsburg Russia. These were built in the 17th century these coasters were built to a height between 70 feet and 80 feet and had a 50 degree drop and we're assisted by wooden supports.

Roller coaster statistics

bigbisquet2 — 2014-04-11 17:18:43 UTC

The largest drop in existence today is the kingda Ka located at 6 flags with a 418 feet drop.

The fastest roller coaster in existence is the formula rossa Ferrari world, Dubai going 149 mph.

The longest roller coaster in existence is called the steel dragon 2000 located in mie japan it is 8,133 feet long.

Corkscrew

bigbisquet2 — 2014-04-12 00:58:02 UTC

The corkscrew is when the coaster goes in a screw like motion around in circles upside down also

Cobra roll

bigbisquet2 — 2014-04-12 01:06:19 UTC

A conra roll is when the coaster goes up then flips into a U shape and then flips back down.

Major question

bigbisquet2 — 2014-04-12 01:10:12 UTC

The reason why the coaster is able to go through the entire track without stopping is because all of the PE that is gained when the coaster goes up a hill is released into KE which keeps it going. Another reason why is that when the coaster goes through twists and turns it has enough PE gained before the stunt to get it through the stunt completely
