Portfolio 2 - Motion, Energy & Momentum Due Thursday April 1 @ 11:59 pmundefinedOops! A note about the Kinematics SkillsOops! A note about the Kinematics SkillsIn the kinematics skills sections I wrote the following phrase "using chart". My bad - Professor A's videos don't use charts! I apologize that this definitely would have been confusing. What I mean by chart is the following:List all the givensList all the assumptionsList all the variables that are zeroExample Problem With "chart":A cannon shoots a cannonball with an initial speed of 8 m/s at an angle of 20 degrees to the horizontal. What is the landing position of the cannonball?x-directionvi = 8m/s*cosine (20)vf = 8 m/s*cosine (20)a = 0 m/s/sdelta-x = ?y-directionvi = 8m/s*sin(20)vf = -8m/s*sin(20)a = -9.8 m/s/sdelta-y = 0 mQuick OverviewQuick OverviewThe portfolio project is where you get to show off what you can do with physics. So far we've learned Forces & Vectors, Motion, Energy and Momentum so that's the focus of this portfolio.At home, you'll set up scenarios (details in instructions). You'll measure everything you can about those scenarios and use those measurements to do calculations and show off your physics skills. A scorecard gives you a list of measurements, calculations and skills that you can choose from. Finally, you'll present all those measurements, calculations and skills in a presentation. This can be a video, a powerpoint, a word document, a sway, a webpage, a padlet...you get to choose your favorite platform.The portfolio is worth 250 points and is due on Thursday, April 1 at 11:59 pm.Portfolio InstructionsPortfolio InstructionsAttached Files: PHY121 Portfolio 2 Scorecard Sp21.docx PHY121 Portfolio 2 Scorecard Sp21.docx - Alternative Formats (19.984 KB) PHY121 Portfolio 2 Instructions Sp21.docx PHY121 Portfolio 2 Instructions Sp21.docx - Alternative Formats (691.208 KB)Download and read this document (I put it in Word and PDF) for the details on the first portfolio. I've also edited it to make a blank scorecard for you to help you keep track of your score as you put your portfolio together. You'll be uploading your scorecard (with checkmarks where you think you've earned points) with your portfolio.Video examples of each scenarioVideo examples of each scenarioI built each scenario at my house and made these videos to show you samples in case the text instructions weren't good enough to help you see what you can do. Don't use my measurements/videos - you are expected to build your own at your home. Good luck! As always, let me know if you have questions.Here's a sample of the Ramp to Flat to Crash scenario:Next is the Table Dive:Finally is the Bounce:OPTIONAL: Using Pivot to Analyze Your Very Own VideosOPTIONAL: Using Pivot to Analyze Your Very Own VideosThe link to the Pivot Lab which you can use to analyze your videos is just below this item.Portfolio 2 Video Analysis (OPTIONAL)Portfolio 2 Video Analysis (OPTIONAL)Who and What Are You Allowed To Work With?Who and What Are You Allowed To Work With?You are expected to finish the portfolio by yourself. Do not do the scenarios with other people and do not share your own results. This is the equivalent of a take-home test where your work is your own.You are allowed to use all our notes and videos on Blackboard to help you as you go. You can also use the textbook and your old Connect work. Do not use other students in the class.If you are stuck, reach out to the professor, she is so happy to help!What if I need extra time?What if I need extra time?Portfolios are the equivalent of exams in the class, so late work is penalized. Portfolio 2 can be up to 1 week late and there is a 10 point per day penalty. If you turn it in after Thursday, April 8th at 11:59pm, your grade will be a zero.FAQ SectionFAQ SectionHello! Here's a helpful FAQ section for you! Right now it's based on questions from past sections but I will add new FAQs from you as needed. Check back here often :)1) I found coefficient of friction by doing the side experiment like in portfolio 1:You don't need to find coefficient of friction anymore, just so you know! There are other ways to figure it out. Please try NOT to use this.2) How should I organize this one?Follow our problem-solving method. First, read over the givens and make some measurements and the video of your setup. Second, draw diagrams, set up charts, Big Ugly equations or momentum equations. Third, show me your calculations and finally always circle your answers. Label the heck out of everything!3) How do I start?Check out our physics problem-solving strategy! It's really great for portfolio help. First explore your scenario and make measurements. Second, set up a diagram. Third, set up your equations that go with the diagram. Fourth, solve for everything you can from those equations. Fifth, maybe there's other things you can figure out (see the scorecard for things you haven't found yet and maybe you can figure out those, too!).4) Can I do all three scenarios? Or...do I have to do all three scenarios?Sure! You can do them all - solve for everything you can! If there's doubles, there's doubles - you get credit only once but think of it as insurance. If you've found that one scenario doesn't give you enough points, then for sure hop over and add the other ones in. 7) Can I get more than 250 points?YES! You can get up to 280 points.When You Turn Things In...When You Turn Things In...Turn in your project and turn in your Scorecard each time. This will help me grade it - if you tell me what points you are going for, then I know what to look for. Makes sense, right? Thanks!If you do a video or Padlet, please post a link to your video in YouTube or your Padlet along with your scorecard. Please do a new Padlet for each portfolio (but within one portfolio, you can do more than one scenario). Do not edit your padlets or videos after the due date! To be safe - don't even load up your Padlet after the due date until you see a grade for it in Blackboard. If you are making a Powerpoint, please use just black and white background - don't get fancy. Fancy = large filesize = may not upload = MONSTER AMOUNTS OF STRESS. Thanks!Upload your portfolio with plenty of time for possible technology glitches. I recommend finishing a day or two early just in case you can't get the files to upload and you need Professor's assistance!
