Is when you are riding on something, and you don't feel any force acting on your body.When you are on a roller coaster, dropping down a hell with a lot of speed, you might feel weightless, because of the inertia and the air acting on your body.

How does a roller coaster continue to move through the twists and turns of a track if it only uses an engine at the very beginning?

A roller coaster only uses engines in the beginning to get up the first hill or slope. Potential and kinetic energy helps the coaster get through the rest of the track. The higher the first drop the more potential energy it will have. Once the cart starts to go down the drop, the potential energy turns into kinetic energy. And then the kinetic energy moves the cart through the rest of the track

It consists of a downward half loop and upward half loop. Since they overlap at the top, they form a pretzel like a shape

In an Immelmann, riders enter a half loop and then go through a half twist and curve out in the opposite direction in which they came

A dive drop is a roller coaster inversion in which a half-inline twist is performed at the top of a lift hill

My favorite roller coaster

# data[].attributes.body
Some people believe that the first real roller coaster was built in 1784 by Russia"s Catherine the Great in the Gardens of Oranienbaum in Saint Peters burg. Roller coasters are popular amusements rides developed for amusement parks and modern theme parks. Disneyland also created the first steel-railed roller coaster in 1859 called the "Matterhorn Bobsleds.

Energy is measured in the unit of joules

Is a body that possesses energy by virtue of being in motion. Heavy objects like roller coasters produces a large amount of kinetic energy

Potential energy is the energy stored by objects. When a roller coaster is going upwards, the potential energy increases, the higher the roller coaster goes, the more potential energy it will have.

The resistance created when 2 or more objects rub or slide against each other is called friction. Friction enables roller coasters to slow their accelerations down.

Is the amount of motion an object has. Momentum equals mass times velocity, any moving object has momentum. When a roller coaster is moving in a high speed, this means that it has a lot of momentum.

G is the measurement of acceleration that is equal to the acceleration caused by gravity. When you are on a roller coaster, g occurs when you are free-falling. Lets say that you are experiencing 5 g"s of acceleration, then you're changing speed will be 50 m/s every seconds.

Centripetal is when you are being pushed in an inwards direction. In a roller coaster, centripetal occurs in the loop, when the force is pulling you towards the center of the loop. Centrifugal is when you are being pushed in an outwards direction. In roller coasters centrifugal occurs when the force in pulling you outwards in the loop.

Acceleration is when an object changes in speed or direction. Acceleration occurs in roller coasters when they are up and they are going down, there the acceleration increases.
