Roller coasters are able to use an engine only at the beginning because the coaster has a great deal of potential and kinetic energy. Since the Coaster has an immense amount of mass, you need to get the coaster on a tall hill. With the tall hill, the coaster builds up a lot of potential energy. Once the coaster is dropped, it then builds up an incredible amount of kinetic energy and inertia. The coaster will go throughout the ride without ease because of the large amount of inertia.

The first roller coaster was created in Russia in the 17th century. The track for the coaster was carved from ice hills. Catherine II loved this ride so much that she had more constructed. Soon this type of ride became popular and was developed into scenic railroads and some of the 19th century mine railroads that we know today. In the 20th century, roller coasters developed the thrill we know today. The first steel roller coaster was created in 1959 and it was called the Matterhorn. Steel became a popular material for roller coasters and was used (and still used) to create thrill rides like Tatsu or X2.

Potential energy is the amount of energy an object has when the object is still. With enough force to move the object and let gravity take its course, all the potential energy is transferred into kinetic energy. The kinetic energy of an object will never be greater than the potential energy. PE is measured in joules, and is greatest on roller coaster at the top of the beginning hill and least at the bottom of the initial drop. Kinetic energy is the energy of an object when in motion, and is measured is joules. An object with a lot of mass with a high speed will have more kinetic energy. On a roller coaster, the coaster has the most kinetic energy at the bottom of the initial drop, and has the least energy at the top of the first hill. The equations for both PE and KE are seen below:

My dream is to ride Formula Rossa: the fastest roller coaster on earth.

Friction is when two surfaces meet and rub up against each other. A great amount of friction will reduce the speed of the object immensely. The more friction there is between a roller coaster and the track, the slower the coaster goes.

The momentum of an object depends on the mass and the speed it has. If two roller coasters are moving at the same speed, but one has more mass than the other, the coaster with more mass has more momentum.

When traveling in a circular motion, there are two forces that apply to the object: a centripetal force that pushes inwards, and a centrifugal force that pushes outwards. When a coaster goes into a loop, the rider is pushed towards their seat.

A g is a unit used to measure how much of gravitational acceleration an object is experiencing. A person riding a roller coaster that assists gravity will be experiencing more g's than usual.

Weightlessness is the sensation of feeling like you weigh nothing, although your weight stays the same. When there is no force pushing up on a rider from the chair and the only other force in play is gravity, the rider will feel weightless.

Acceleration is the rate at which an object changes speed. A roller coaster that changes speed quickly has a fast acceleration. A roller coaster that takes a long time to change its speed has a slow acceleration
