How does a roller coaster get through the ride with only using an engine at the beginning? 

# data[].attributes.body
A roller coaster needs an engine at the beginning because gravity can't start the roller coaster. When the roller coaster goes up it is gaining potential energy but when it goes down it uses kinetic energy.

Roller Coasters started as early as the 17th century. It all started in Russia, they constructed them on mountains of ice and also had wooden supports. As time went on roller coasters got more and more advanced. A cool fact is that Matterhorn Bobsleds was the worlds first tubular steel rollercoaster

Potential & Kinetic Energy in Roller Coasters

# data[].attributes.body
The potential energy rises when the coaster is heading upwards because it is possessing all the energy it takes to go up. So, when it finally goes down it goes down with as much energy that it took to come up.

# data[].attributes.body
Kinetic Energy is also the amount of energy that an object possesses but in this case the object is in motion. If another object is obstructing the moving object, the moving object will release it's energy to the other object.

# data[].attributes.body
Potential Energy is energy stored in an object, based on its position related to others. Potential energy is energy stored up and will let out how ever much it has when fallen.

# data[].attributes.body
Friction is the resistance an object encounters when moved. Roller coasters have friction with the wheels and the rails. There is also more friction when there is a turn or more weight.

# data[].attributes.body
Weightlessness is a sensation when your falling. On a roller coaster you get this sensation when your taking a huge dive downward.

# data[].attributes.body
The amount of stuff that is moving and how fast the stuff is moving. A roller coaster taking a plunge has more momentum than another roller coaster going upwards.

# data[].attributes.body
A g is a unit of acceleration caused by gravity. You might fell some g's on a roller coaster because it is changing acceleration so many times.

# data[].attributes.body
Centripetal force is when an object is pushed in an inward motion. When a roller coaster goes through a sharp turn the passengers are pushed toward the center of the turn because of this force.

# data[].attributes.body
Acceleration is when an object changes their speed or direction. When an object does either of these things it is known as acceleration. Roller Coasters have a lot of acceleration. When the ride takes a plunge downwards or has a very sharp turn that is all acceleration.
