The surface resistance to relative motion, as of a body sliding or rolling. Design, build, and refine a device that works within given constraints to convert one form of energy into another form of energy. K - If not dropped smoothly, the marble may bounce past the first inches of the path, not attain the calculated velocity and not pass the first hill. a part of a line that is bounded by two distinct end points, and contains every point on the line between its end points Then they tested the path and if the marble stopped or flew away, they modified the path until the marble was able to complete the entire path. Graph the model of the roller coaster using the graphing calculator. Be careful to not let glue or tape get on the interior channel of the pipe insulation because that interferes with the rolling marble.

Rubric title Performance Task-Design a Roller Coaster Car. Doing this completes the mathematically designed Russian Mountain roller coaster path prototype so it is ready for testing. If so, ask them to briefly describe what they did. The student analyzes and uses functions to model real-world problems. plane figure with five straight sides and five angles tangent line: The straight line that touches a curve at a point without crossing over. Determine the height of these vertices using equation (1): the marble has its maximum height at x0 = 0 (origin), and the marbles initial velocity vi at that point is zero: Now it is necessary to evaluate equation (1) along the parabolic path (3). When friction is present, the mechanical energy (ME) of a system: kinetic energy (K) + potential energy (U), is not constant. 12), use a problem-solving model that incorporates analyzing given information, formulating a plan or strategy, determining a solution, justifying the solution, and evaluating the problem-solving process and the reasonableness of the solution; 1 / 105. small angle which is less than 90.
