# Phy 101 qualitative description of your rube goldberg device step

Must use algodoo and create a simple step or stage and describe.

Prompt:

The final project for this course is the creation of an Analysis Report. For Milestone One you will submit the Qualitative Description of your Rube Goldberg Device Step.

This milestone is due in Module Three and you will provide a basis for the development of the final project by using the concepts from the class to describe in words the interactions that explain the motion observed in the selected stage of your device. If you have not begun the design of a device, provide a reference to a device that you have found. Your submission will describe qualitatively what is going on during the selected step and at the transitions to/from the neighboring steps.

Specifically, the following critical elements must be addressed:

I. Step Selection: Select a step or stage in the Rube Goldberg device. Provide a concise description of the step.

II. Selected Step A. Initial Velocity: Calculate the initial velocity of the object in the selected step. What does the initial velocity of the object tell you about the behavior of the object? B. Velocity and Force Calculations: Calculate the change in velocity that would be observed based on kinematics and force principles. Then, use Newton’s Second Law to calculate the force acting on the object.

Guidelines for Submission: Your paper should be submitted as a 1- to 2-page Microsoft Word document with double spacing, 12-point Times New Roman font, and one-inch margins.

Critical Elements Proficient (100%) Needs Improvement (75%) Not Evident (0%) Value Step Selection Selects and concisely describes step in Rube Goldberg device Selects and describes step in Rube Goldberg device but description is wordy or vague Does not select and describe step in Rube Goldberg device 20 Selected Step: Initial Velocity Accurately calculates the initial velocity of the object in the selected step and clearly explains how the initial velocity can be used to analyze the behavior of the object Calculates the initial velocity of the object in the selected step and explains how the initial velocity can be used to analyze the behavior of the object, but calculation contains inaccuracies or explanation lacks detail or clarity Does not calculate the initial velocity of the object in the selected step

35 Selected Step: Velocity and Force Calculations Accurately calculates change in velocity and force acting on an object Calculates change in velocity and force acting on an object but with gaps in accuracy Does not calculate change in velocity or force acting on an object 35
