Acceleration= increase in the rate or speed of something

Centripetal= moving or tending to move toward the center

Centrifugal force= an apperant force that acts outward on a body moving

Around a center arising from the body's inertia

G=A g is a unit of acceleration equal to the acceleration caused by gravity.

Momentum=Momentum pertains to the quantity of motion that an object possesses.

Weightlessness= being without apparent weight as a freely falling body

These all apply to roller coasters because as you ride the roller coaster you experience

Each of these properties

Friction is a force that resists the motion of an object this applies to roller coasters

 because when you ride a roller coaster u try to resist some of the motions

Potential energy is when a object has the to move by itself

kinetic energy is an energy an object has when its moving

potential energy= mass x g x height

PE= m h x (9.8 m/s/s)

kinetic energy= 1/2 x mass x velocity2

KE=1/2mv2

Energy is measured in joules

When the roller coaster goes up it uses more potential energy

 but when it goes down it use Kinect energy

 The French then took this idea and made it better, using waxed slides and adding

 wheels to the sleds, creating a coaster a roller dose all of these turn because it is 

mounted on the track an there is a force being applied on the coaster

1st loop: 75 centimeters

2nd loop: 70 centimeters

Start drop: 1.5 meters/150 centimeters

Total coaster length: 7.4 meters/740 centimeter

Individual tube length: 1.85 meters/185 centimeters

Total time: 5.76 seconds

Fastest part time: 0.56 seconds

Mass of marble: 0.0055 kilograms

PE=mass x height x 9.8. Answer=1.29cm/kg

KE @ fastest point: KE=1/2mv^2=0.5 x mass of marble x velocity squared. Answer=29.52
