In this case, the friction on the marble is more because many points of contact exist, instead of just one, as estimated in the calculations, and then the marble stops sooner. So we made a point to always use marbles with diameters less than the pipe insulation internal diameter. You are welcome to contact the author, Miguel R. Ramirez, at mramirez2 galenaparkisd. For lower grades, make simplifications in the path design process, but not in the physics or calculations to test the models.
Instructor guidance for this approach:. For students with no calculus background, have them sketch their roller coaster paths on graph paper A and use an alternate provided spreadsheet B to interactively visualize their designs and estimate velocities and friction forces along the path. In addition, the velocities along the path are automatically calculated and displayed. Any NUM! The no-calculus spreadsheet also estimates the friction force along every segment of the path using a non-calculus alternative to formula 15 :. Excel: Get Started with Formulas and Functions.

Summary Students apply high school-level differential calculus and physics to the design of two-dimensional roller coasters in which the friction force is considered, as explained in the associated lesson. In a challenge the mirrors real-world engineering, the designed roller coaster paths must be made from at least five differentiable functions that are put together such that the resulting piecewise curving path is differentiable at all points.
Once designed mathematically, teams build and test small-sized prototype models of the exact designs using foam pipe wrap insulation as the roller coaster track channel with marbles as the ride carts. Project constraints students must consider include: initial cart velocity of zero at the highest point , and final path end velocity of zero. The design must be efficient enough that the initial potential energy of the body is sufficient for it to complete the entire path. To achieve an efficient design, students use a formula obtained in the associated lesson—one that gives the velocity of a spherical body rolling on a curved path when friction is present. To conclude, teams summarize their procedures, designs, results, and theory-vs.
This activity and its associated lesson are designed for AP Calculus. Engineering Connection With their breathtaking elevation changes and speeds, spine-chilling roller coasters rides are the star attractions of amusement parks. Grades 9 - 12 Do you agree with this alignment? Criteria may need to be broken down into simpler ones that can be approached systematically, and decisions about the priority of certain criteria over others trade-offs may be needed. When evaluating solutions it is important to take into account a range of constraints including cost, safety, reliability and aesthetics and to consider social, cultural and environmental impacts. New technologies can have deep impacts on society and the environment, including some that were not anticipated.
Analysis of costs and benefits is a critical aspect of decisions about technology. At the macroscopic scale, energy manifests itself in multiple ways, such as in motion, sound, light, and thermal energy. Although energy cannot be destroyed, it can be converted to less useful forms—for example, to thermal energy in the surrounding environment. Criteria and constraints also include satisfying any requirements set by society, such as taking issues of risk mitigation into account, and they should be quantified to the extent possible and stated in such a way that one can tell if a given design meets them. Modern civilization depends on major technological systems. Engineers continuously modify these technological systems by applying scientific knowledge and engineering design practices to increase benefits while decreasing costs and risks.

Students will develop an understanding of engineering design. Students will develop an understanding of the relationships among technologies and the connections between technology and other fields of study. Students will develop an understanding of the attributes of design. The design process includes defining a problem, brainstorming, researching and generating ideas, identifying criteria and specifying constraints, exploring possibilities, selecting an approach, developing a design proposal, making a model or prototype, testing and evaluating the design using specifications, refining the design, creating or making it, and communicating processes and results.
Design problems are seldom presented in a clearly defined form. The design needs to be continually checked and critiqued, and the ideas of the design must be redefined and improved. Requirements of a design, such as criteria, constraints, and efficiency, sometimes compete with each other. Established design principles are used to evaluate existing designs, to collect data, and to guide the design process. Engineering design is influenced by personal characteristics, such as creativity, resourcefulness, and the ability to visualize and think abstractly.
A prototype is a working model used to test a design concept by making actual observations and necessary adjustments. The process of engineering design takes into account a number of factors. Use computers and calculators to access, retrieve, organize, process, maintain, interpret, and evaluate data and information in order to communicate.

The student uses process standards in mathematics to explore, describe, and analyze the attributes of functions.
The student makes connections between multiple representations of functions and algebraically constructs new functions. This is because not all of the potential energy is converted to kinetic energy. Some of the potential energy is "lost" in other energy conversion processes. For example, the friction of the wheels and other moving parts converts some of the energy to heat. The cars also make noise as they move on the tracks, so some of the energy is dissipated as sound. The cars also cause the supporting structure to flex, bend, and vibrate. This is motion, so it is kinetic energy, but of the track, not the cars. Because some of the potential energy is dissipated to friction, sound, and vibration of the track, the cars cannot possibly have enough kinetic energy to climb back up a hill that is equal in height to the first one.
The way that physicists describe this situation is to say that energy is conserved in a closed system like a roller coaster. That is, energy is neither created nor destroyed; there is a balance between energy inputs to the system raising the train to the top of the initial hill and energy outputs from the system the motion of the train, its sound, frictional heating of moving parts, flexing and bending of the track structure, and so on.
You can investigate the conversion of potential energy to kinetic energy with this project. You'll use foam pipe insulation available at your local hardware store to make a roller coaster track. For the roller coaster itself, you'll use marbles. There are as many possible variations to this project as there are twists and turns on a great roller coaster ride, but a good place to start is to see how much initial height you need in order to have your marble successfully navigate a loop in the track.
You'll use the same size loop for each of your tests, but you'll add or subtract track before the loop so that you can change the initial height where the marble starts. For each track configuration, you should try at least 10 separate tests with the marble to see whether it can loop the loop or not. You should also measure the slope of each track configuration. The rise is the height of the starting point, and the run is the horizontal distance from the starting point to the beginning of the loop.
Figure 1. The illustration above shows how to measure "rise" and "run" in order to calculate the average slope of the track leading in to the loop. How much height rise will be required to successfully navigate a given loop size? A foam roller coaster for marbles is easy to build, so try it for yourself and find out! To do this project, you should do research that enables you to understand the following terms and concepts:. Note: Use the utility knife with care. A fresh, sharp blade will make cutting the insulation easier.
Here are just a few of many possible variations on this project. Perhaps these will stimulate your thoughts about other experiments you could try:.
