We named it "Daranna's Le Flame O' Coaster". In total it was 100 cm from the top to the ground. The total length  was 7.4 and the total time that it took to complete was five seconds.

If a roller coaster only uses an engine in the beginning how can it still continue to move without it? Well, the two major parts that take place into making that happen is kinetic energy and potential energy. If the cart of the roller coaster was about to go down a large or steep drop then the kinetic energy would result as potential energy. The kinetic energy helps move the cart along the path and through curves and loops

Believe it or not but America has some of the world wide breaking records for roller coasters. Kingda Ka found at Six Flags Great Adventure takes first place for tallest steel roller coaster at 456 ft! It also ranks at number one for longest steel roller coaster drop with 418 ft!

It goes all the way back to Russia in the 15th century. Originally they were first made out of hills of ice and the slides were built 70-80 feet high. They had 50 degree drops with reinforced wooden support systems. A group full of historians believe that roller coasters were first built in France though, and soon other countries and places caught on.

Energy is measured in joule. Named after James Precott Joule and his scientific experiments.

Energy is a property of objects, and can be transferred among fundamental objects. It is the strength needed for one to obtain physical or mental activity.

Friction is the outcome of what happens when two objects encounter each other on their surface. In a roller coaster, friction plays the part of slowing down the cart, friction is also why sometimes the track would get smaller.

All of these forces of physics all have very much to do with the making and works of roller coasters. The structure of many roller coasters have narrow tracks, deep drops, loops, and the ability of going upside down. Acceleration helps increase the speed of the roller coaster when running on the track, making it hard to fall off. The two forces centripetal and centrifugal both have very big parts in roller coasters. Centripetal force helps with sharp turns and curves while Centrifugal force helps with loops in the track. G force would help pull you down while an acceleration force would help push you up, they both work together in a way. The force momentum helps with thanking of movement that would take place on the cart while it is running on the tracks. Weightlessness occurs when there is no apparent weight that can occur on the cart. Acceleration force, weight, and gravity weight all work with each other when a cart is about to go into a loop. The weight and acceleration force are pushing down on the track while the gravity weight is pushing up.
