Acceleration

cifuentesxiomar — 2014-04-07 19:10:52 UTC

Acceleration relates to rollercoasters because not only are they changing speed but also direction throughout the ride like when there going up and down a hill it accelerates and decelerates.

Centripital Force

cifuentesxiomar — 2014-04-08 03:51:04 UTC

When the car of the roller coaster is being pulled inward towards the loops it acting by centripital force.

Centrifugal Force

cifuentesxiomar — 2014-04-08 03:57:13 UTC

As the force is outward pushing in like newtons 3rd law every force has an equal and oppisite force.

Momentum

cifuentesxiomar — 2014-04-08 17:32:25 UTC

Momentum is a certain amount of velocity and motion. The amount of stuff that is moving in the Rollercoaster is the amount of velocity.If an object is moving slow it means it has less momentum if an object is movng fast it has more momentum.

Weightlessness

cifuentesxiomar — 2014-04-08 20:16:55 UTC

When you sitting on the Roller coaster and it's going at a high velocity and as the ride is movie you feel a lift between the seat and your body.It makes you feel weightless because you don't feel your full on weight on the seat.

Friction

cifuentesxiomar — 2014-04-08 20:24:39 UTC

Friction is a force of two surfaces that pass right past each other the Rollercoaster wants o minimize friction but needs enough so that the car stays on the track.

"G"

cifuentesxiomar — 2014-04-08 20:31:46 UTC

A G is an acceleration that's caused by gravity causing objects to change there speed at rates like10m/s2 when roller coasters go from a low speed to high speed.Like when there going up and down hill as the Rollercoaster is going up it has a low speed and as it's going down it has a height speed.

Potential Energy formula

cifuentesxiomar — 2014-04-08 20:41:39 UTC

Potential energy=mass x g x height

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

Kinetic Energy formula

cifuentesxiomar — 2014-04-08 20:49:25 UTC

Kinetic Energy=1/2 x mass x velocity2

kinetic math

cifuentesxiomar — 2014-04-09 02:50:57 UTC

A 12 kg dog is running at a velocity of 5m/s how much kinetic energy does it have?

KE=0.5xMassxVelocity^2

=150 joules

Potential Math

cifuentesxiomar — 2014-04-09 02:56:07 UTC

If you lift a 50N watermelon to the top of a 2m fridge how many potential energy does it have?

PE=Mass x 9.8 x height

PE=50 x 9.8 x 2 = 982 joules

PE&KE

cifuentesxiomar — 2014-04-09 03:05:29 UTC

Potential energy and kinetic energy change throughout the roller coaster because as the roller coaster goes up ward its using alot of potential energy. when its going down ward it uses kinetic energy as well as when its going around the loops it contains kinetic energy.Potential energy is energy stored that decreases or increases depending on the condition.

HISTORY

cifuentesxiomar — 2014-04-09 03:16:26 UTC

Rollercoasters were first built in the 15th century many roller coaster were made to be really big safe and fast.Many roller coasters were made for entertainment because of how fast the ride traveled and many kids like height today they are still used as entertainment.

Roller coaster Element

cifuentesxiomar — 2014-04-10 00:28:18 UTC

Oneof the all time elements of a roller coaster is the pretzel loop i know that when i read ths it was about the periodic table but no this element is one of the things that make you throw up when your on the ride.The loop is shaped like apretzel because many for the entertainment but most likely it makes you sick but its the funest part.

Famous rollercoater

cifuentesxiomar — 2014-04-10 04:47:51 UTC

Scream from six flags is the most known ride that i hear alot from known as the fastest ride getting its name from that terror of this ride going at no lower that 98 miles per hour on the ride and in loops.This ride has a sudden drops at 148 miles per hour.

Weightlessness

cifuentesxiomar — 2014-04-10 05:00:56 UTC

The roller coaster stays in motion because not only is it still using kinetic and potential energy but the seats are providing an un balanced force like you are 150 pounds on the rollercoaster you will weigh about 300 pounds.When your on the coaster you feel weightlessness known as g's.Thjats why as your on on the rollercoastrer you feel the seperation of your body and the seat.

How long is the track?

cifuentesxiomar — 2014-04-11 01:37:30 UTC

our roller coaster wasnt working out but we made a coaster for kids named the kiddy coaster its length was 5.55 cm and the height was 197 cm

Energy

cifuentesxiomar — 2014-04-11 17:24:01 UTC

Energy is measured in joules.
