Group 1About usHey guys,
We are Catherine, Fleur and Nikita, and we will tell something about ourselves over here. |
NikitaI'm 13 years old and I like doing ballet and playing hockey. I would like to be a writer or dancer when I'm older.
|
CatherineI'm 12 years old and I like doing drama and writing. I would like to be a pediatrician when I grow up.
|
FleurI'm 13 years old and I like figure-skating and playing piano.

Our plan
We will do a research about engineering (in houses and rollercoasters). We will have an interview with an engineer and a builder. We will also try to find out which material is the best to build on.
This was our research:

Cis
Hey!
My name is Cis and I’m 12 years old.
My hobbies are playing the saxophone and playing football. I also like to be with friends and to travel and meet people and cultures from different countries.
My favorite school subjects are Physical Education (PE), Physics and Mathematics.
After college I would like to go to the Technical University.

The plan
Our plan is to look what role mathematics plays in the architecture of rollercoasters. Our plan is to go to Walibi Holland (a park with rollercoasters), and interview some people who work there.
We arranged our plan. We instead of went to Walibi we called Walibi Holland.

The research question
Do engineers for rollercoasters use formulas?
Hypothesis
We think they do because otherwise it could be dangerous.
The research
So we called a funpark in the Netherlands called Walibi. The girl we talked to gave us the name of a big German rollercoastercompany. The name of the company is MACK rides. We found the phonenumber of the technical manager. His name is Günter Burger. We are going to ask him if he uses formulas in making rollercoasters.
On the Internet we already found one formula: gravitational potential energy= weight rollercoaster x acceleration (=9,8m/s^2) x height
We found this on www.real-world-physics-problems.com

The results
We tried to call mr. Burger, but he didn't receive the phone call. So we searched on the internet to find some formulas. This is what we found:
Gravitational potential energy = mass x acceleration x height
Kinetic energy = 1/2 x (mass x speed)²
Gravitational potential energy = Kinetic energy
Thus, mass x acceleration x height = 1/2 x (mass x speed)²
Speed = √(2 x acceleration x height)
Centripetal acceleration experienced by the riders twisting = rate of twist in radians/seconds² x radius of the twist
Centripetal acceleration experienced by the riders going around a loop = speed²/radius of the loop
Legend:
Acceleration equals 9.8 m/s² on earth's surface.
Kinetic energy is the energy of motion, observable as the movement of an object.
A centripetal acceleratioin is an acceleration that makes an object follow a curved path.
Gravitational potential energy = mass x acceleration x height
Kinetic energy = 1/2 x (mass x speed)²
Gravitational potential energy = Kinetic energy
Thus, mass x acceleration x height = 1/2 x (mass x speed)²
Speed = √(2 x acceleration x height)
Centripetal acceleration experienced by the riders twisting = rate of twist in radians/seconds² x radius of the twist
Centripetal acceleration experienced by the riders going around a loop = speed²/radius of the loop
Legend:
Acceleration equals 9.8 m/s² on earth's surface.
Kinetic energy is the energy of motion, observable as the movement of an object.
A centripetal acceleratioin is an acceleration that makes an object follow a curved path.
ConclusionSo the answer to our research question is: Yes, they use different formulas to build rollercoasters. So our hypothesis is correct.

Comparison
We couldn't really compare our research with other schools because we did something else.
