Roller Coasters
A famous amusement ride, the roller coaster is an elevated railway usually with steep inclines and sharp curves, including one or more vertical loops. Patented by LaMarcus Adna Thompson, the first underfriction roller coaster was developed in 1919.

How can you be in motion and not in motion on a roller coaster at the same time?
At the top of one of the hills, you are in horizontal motion,
but your vertical motion is zero.
Same for a child at the bottom of the arc on a park swing.
Same for anyone at the highest or lowest point on a moving Ferris Wheel.
What wooden roller coaster has the longest duration?
The longest-duration wooden roller coaster is The Beast at Kings Island Park. The track is 7,359-feet long. Kings Island is a 364-acre park located in Mason, Ohio.
What features do most roller coasters have?
All roller coasters have at least one hill and one drop. Most roller coasters also have turns as well. Inversions (going upside down) is typical on steel coasters and rare on wooden ones. Their is always some way to start a roller coaster, a chain or hydraulic launch systems are some. Brakes are on every roller coaster as well.
"Nothing But Trouble" (1991). It starred Chevy Chase, Dan Aykroyd, John Candy, Demi Moore. It was also directed by Dan Aykroyd.
Which roller coaster will replace the big bad wolf?
A park spokesperson said the following : "Park officials are reviewing several design concepts for a new park attraction to replace The Big Bad Wolf, but no announcement is planned at this time."
Is the millennium force scary?
No way! I go to Ceder Point for vacation 1 time year. I run straight to Millenium Force and I have a great time. It is so smooth. But when your on the top of the lift hill...... DONT LOOK DOWN! My brother goes on it with me. And hes in 4th grade! Critics say it is the 6th best coaster of 2009. You should really go on it.
HOPE I HELPED!
Hello there. The feeling of fluttering you have mentioned above sounds like heart palpitations. These are very common and most are benign and not heart problem related. However if you have a heart condition or there is a history of heart problems in your family OR if your experiencing other symptoms along with the palpitations - then it is advisable you seek medical advice and speak to your doctor.
How many types of roller shutters are there?
"Types of roller shutters include: built-on roller shutter doors, integrated roller shutter, roller shutter with tilting laths, manual, manual tape, electric, and fire shutter."
What does life is a roller coaster which everyone has to go through mean?
Your life has many ups and downs, but everyone has them.
Why is the first hill the highest?
For a roller coaster, it is the highest so it has enough momentum to finish the ride.
This is only for a wooden roller coaster. Some modern steel rides have self-propelling LIM circuits that blast the riders instantly from 0 to over 60 mph, up and over hills, and around to the station. (Some examples are the tallest and fastest ride in the world as of 2009- Kingda Ka in Six Flags New Jersey and Top thrill Dragster in Cedar Point, which holds the number 2 spot for excitement.) X in Magic Mountain, Superman:Ride of Steel, and Millennium Force are all modern rides that still use the chain-lift hill system. But these don't run on a real "chain" and aren't powered by a motor, but computers and fast gears that take the rider from ground level to over 200 feet in seconds. People think that corkscrew and vertical loop coasters are unsafe because there's a chance the rider could fall off. Not only are they held in one piece by the most complex and strong network of supports, but also by gravity itself. So even if the ride did fail, kinetic energy will do the job by forcing the train upwards. This is an opposing gravity effect. This can be done in experiments at home. Take a base with a string to hold on to. Take a cup of water and place it on the base. You can swing it in a circle upside down without spilling (until it looses its momentum of course.) The force keeps the water from coming out. Water in itself has many unique properties, allowing it to bend with the forces of gravity. Steel is denser than water, so you would expect a paper clip to sink. But if you gently let it sit on the surface it will float. It acts as a skin. The clip will even leave an indent in the water until it is taken out. Water doesn't overflow a drink very easily, because it has a knack to attach to itself. The hydrogen and oxygen molecules are unbalanced. If ice was denser than liquid water (it's not, that's how ice cubes work) then it would be like most other elements, freezing from the bottom up. If this happened, no life would exist in lakes in winter. What this all has to do with your question i don't know. There is today's science lesson. Come back tomorrow, as I will demonstrate the string theory to you!
Does wooden roller coasters rot?
They could. But odds are they add an anti-rotting agent or check it daily to be safe.
according to Newton's second law the force experienced by an object is directly proportional to its rate of change of momentum.
F = m(v-u) /t
where:-
F = the average force applied
m = the mass of the object
u = the initial speed
v = final speed
t = time
thus when rearranged when u = 0
50000 x 12 = 30000(v-0)
60=3v
v=20ms-1
speed = 20 thus momentum is 100000 Kgms-1
Is a roller coaster an example of newtons third law?
Not really. Newtons laws basically are:
1. an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by a force
2. force equals mass times acceleration
3. every reaction has an equal and opposite reaction
Roller coasters are, however, a good example of conservation of energy.
