A roller coaster is a type of amusement ride that employs a form of elevated railroad track designed with tight turns, steep slopes, and sometimes inversions. People ride along the track in open cars, and the rides are often found in amusement parks and theme parks around the world. LaMarcus Adna Thompson obtained one of the first known patents for a roller coaster design in 1885, related to the Switchback Railway that opened a year earlier at Coney Island. The track in a coaster design does not necessarily have to be a complete circuit, as shuttle roller coasters demonstrate. Most roller coasters have multiple cars in which passengers sit and are restrained. Two or more cars hooked together are called a train. Some roller coasters, notably Wild Mouse roller coasters, run with single cars.
I'm not sure if this question belongs to this forum or advanced phsyics.. but since I'm still in high school, I think this is the right forum.
I'm doing physics questions based on roller coaster and am just a little bit confused on how to answer some questions.
You know :
Mass of each...
Hey,
Can anyone show me a site that talks about the physics equations involved in the zero-g rolls of a roller coaster?
I know they are called heartline spins and resemble a barrel roll, but I need help with the physics equations.
Thanks!
A roller coaster car of mass 1216 kg slides on
a frictionless track starting at a distance 32 m
above the bottom of a loop 25 m in diameter.
The acceleration of gravity is 9.81 m/s^2
If friction is negligible, what is the magni-
tude of the force of the track on the car when
the car is...
A roller coaster gets over the first hill of height 50.0 meters moving less than 1 meter per second. Then would it stay with the track if it were not mechanically held on to it at the top of the loop the loop. (The top of the loop the loop is 35 meters and it goes 17.1 meters per second at that...
Roller coaster Vel. Initial=10m/s, Height initial=100m, and the mass of the coaster is 1000kg all at the starting point (*).
Have to find the speed of coaster at point A, point A's height is the same as the starting points, b is 1/2 of a's height, c's height is zero.
Coaster kinda looks like...
I’m having trouble with my physics lab this week. Here is the problem which we are trying to solve:
What is the minimum height at which you can release a ball in order for the ball to just make it around a loop?
The ideal situation for this would be to drop it from a height at which the normal...
A roller coaster car of mass 1500 kg starts a distance H = 25 m above the bottom of a loop 15 m in diameter (Figure 7-24). If friction is negligible, find the downward force of the rails on the car when it is upside down at the top of the loop.
Uhm iwell i figured out the KE and the PE at the...
This is another problem a buddy of mine and I cannot figure out if our life depended on it. Here's the question word for word:
A roller coaster track has a hill with a circular curve of radius 20 m. Find the speed of the roller coaster at the top of this hill.
Started by drawing a picture...
Show that a roller coaster with a circular vertical loop. The difference in your apparent weight at the top of the circular loop and the bottom of the circular loop is 6 g's-that is, six times your weight. Ignore friction. Show also that as long as your speed is above the minimum needed, this...
i know and think that the when the mass inreases, the speed of the coaster does not change... this is according to researching on some sites simulators... it hinkt that's right...
and because the speed esont change, the time doesn't change?
but when i think about it more, I am nto sure...
When a roller coster does a loop, what forces do we feel at the top of the loop?
I think it's only the normal force. There is MG acting downwards, and also the normal force of the rollercoster seat that is pushing towards the center of the coster.
Is this normal force the same as the...
A roller coaster car crosses the top of a circular loop-the-loop at twice the critical speed.
What is the ratio of the car's apparent weight to its true weight?
from my notes i have that Velocity_critical= squareroot ( r w / m)
v = sqrt(rw/m)
so what i did was multiply v times...
A car in a roller coaster moves along a track that consists of a sequence of ups and downs. Let the x-axis be parallel to the ground and the positive y-axis point upward. In the time interval from t=0 to t=4 s, the trajectory of the car along a certain section of the track is given by

Hi everyone,
I am currently doing a roller coaster project in school, where a marble must travel around a track of our design within certain dimensions. Easy right? Well, yes, but not since I plan on having the best roller coaster in the class. (the grades are put on a curve, best coaster...
I'm a gr 11 physics student at Ashbury College (Ottawa, Canada) and our class (in multiple teams) has been entered in a roller coaster contest, held by Wonderland. (A theme park in Ontario, Canada).
My friends and I are determined to win this contest, and I am sure that the ideas of those in...
I have a group depending on me.. and I have no idea where to begin with these problems... they're additional calculations connected with a rollercoaster project we're doing... our average friction is .0212 N if that is needed... someone please direct me to some solution you have no idea how much...
Hello, everyone. I'm new here at the forums, and I've got a little physics problem I'd like your input on:
"A roller coaster reaches the top of the steepest hill with a speed of 6.0 km/h. It then descends the hill, which is at an average angle of 45 degrees and is 45 m long. What will...
Hi we're doing a project in class where we make roller coasters and we test them out by sending a marble down them.
As a bonus question my teacher asked why there would be an error in the calculations we do (finding speed at different locations of the roller coaster) if we're using a...
In my 11th grade physics class we had to design and make a marble roller coaster. Now we have to write a paper explaining how one aspect of our coaster works. I chose to do the jump, but I really have no idea how to explain how this works using physics. Can someone please help me? Also you can...
i don't even know how to derive an equation for this problem i am confused if someone would just show me how to derive the equation that would be appreciated not looking for an answer just how to do it.
A roller coaster is designed so that after a large drop, the cars enter a circular path...
I would appreciate any hints or help in solving the following two physics problems. At this point I am stuck after trying to solve the problems for a while.
1. Apollo astronauts hit a golf ball on the moon 180 meters and 30 meters on earth. Assume that the swing, launch angle, etc are the...
Hi everyone,
Suppose I have a track that starts at a height h, goes down (not a vertical fall, but gradually in a slope), enters a circular loop of radius r (the loop is 'laying' on the ground so the top of the loop is at a height 2r from the ground) and then continues at ground level...
Alrighty.. I was just wondering if you'd be able to help me out with a quick little problem I have. For physics we had to build a roller coaster, i am in the process of calculating the work done by the frictional forces throughout the course. Here's the question; In loopdy loops, when the marble...
For my science fair project, I am testing the effect of changes in mass on the time it takes a car to complete a roller coaster track. The track is made of hotwheels track and has an initial ramp, two turns and a loop. I used the same car both times (once without added weight and once with an...
Hi, part my project involves designing a vertical loop on a roller coaster that is not to exceed 5 G. The weight of the coaster is 4.5 x 10^4 N. But, I don't know how high I need to start the coaster so that there is enough mechanical energy to make it through the loop. I read online that the...
The mass of the coaster is 800 kg
The lift hill is 18 m highabd it goes up the lift hill at 2.50 m/s
The second hill is 5.5m high.
Wants to know the speed at the top of the second hill.
do i really care about the weight of the car?
This is what i have so far
PEtop1 +KEtop1 = KE bott...
Hello, I'v lately been intrigued by roller coasters as of late (notice my prior post about that app)
I havnt been able to find any good websites to explain the physics of roller coasters in detail. I know of-coarse that it works on conservation of energy, that the initial potential energy is...
Assuming the roller coaster is towed to the top of the hill on the left-hand side of the diagram and released. How would the conservation of energy work. I know that at the top of the first hill there would be P.E. and as it gradually rolls down the K.E. takes over. But how about as it...
