Acceleration

noahtumblin — 2015-04-07 18:44:25 UTC

Is when an object changes speed, on roller coasters the speed goes from really fast to really slow all the time.

Centripetal

noahtumblin — 2015-04-07 18:46:59 UTC

Is motion along a curve or circle, on roller coasters there is a lot of loops and flips.

G

noahtumblin — 2015-04-07 18:50:46 UTC

G is a unit of acceleration equal to the force of gravity

Momentum

noahtumblin — 2015-04-07 18:51:56 UTC

Momentum pertains to the quantity of motion, on roller coasters there are steep drops and the momentum carries the roller coaster down it.

Weightlessness

noahtumblin — 2015-04-07 18:53:14 UTC

No longer feel an external force acting upon their bodies , when you ride a roller coaster and your doing a flip at times you can feel weightless

Related to Roller Coasters

noahtumblin — 2015-04-07 18:54:46 UTC

These are related to roller coasters because when you ride a roller coasters all of these forces are happening.

Friction

noahtumblin — 2015-04-07 18:57:40 UTC

Friction is the force that resists the movement of an object. This relates to roller coasters because the breaks prevent the Roller coaster from going to fast.

Kinetic Energy

noahtumblin — 2015-04-07 19:13:18 UTC

Is the energy possessed by an object because of its motion

Equations

noahtumblin — 2015-04-07 19:24:37 UTC

potential energy= mass x g x height

pe= mh x (9.8 m/s/s)

kinetic energy= 1/2 x mass x velocity2

ke= 1/2mv2

noahtumblin — 2015-04-07 19:32:20 UTC

What is the unit of energy?

noahtumblin — 2015-04-10 18:36:10 UTC

How do KE and PE change through out the roller coaster?

noahtumblin — 2015-04-10 18:39:00 UTC

In a roller coaster there is a lot up going up and down and when the roller coaster is going up really high there is a lot of potential but when you go down the roller coaster there is a lot of kinetic energy .

The history of the roller coaster

noahtumblin — 2015-04-10 18:45:58 UTC

the roller coaster can date back all the way to 17th century in Russia where they would construct ice slides. The oldest roller coasters descended from Russian Mountains. In the 1850's a mining company in Summit Hill, Pennsylvania constructed the Mauch Chunk gravity railroad. In 1959 Disney Land introduced a new design breakthrough in roller coasters with the Matterhorn Bobsleds.

Roller Coaster Statistics

noahtumblin — 2015-04-10 18:59:47 UTC

The longest roller coaster is located is the Steel Dragon 2000 located in Japan. The track is 8,133 feet. There is a roller coaster in 6 flags that reaches speeds of 130 mph.

Major Question

noahtumblin — 2015-04-13 17:03:46 UTC

The reason why roller coasters can move through twists and turns when it only uses an engine at the beginning is because of acceleration. Since the roller coaster is moving so fast momentum carries it through twists and turns. Also potential energy is another reason why roller coasters can go through loops without engines.
