 * 1. PDF: Solving the spring equation numerically.** [[file:SolvingTheSpingEquationNumerically.pdf]]
 * 1) File Author: Submitted by David Derbes (with citations)
 * 2) Type of File: The spring equation a = -(k/m)x is solved numerically, following the same routine as Feynman’s in his Lectures (vol. I, Chap. 9) - pdf

This is just a version of the demonstrations/lectures we all do for spring constants. It's short, but at least the students are doing it themselves. Submitted by: Mark W. Hossler, mhossler@landmark-cs.org
 * 2. Spring Constants: Two Ways.** [[file:Spring Constant.pdf]]


 * 3. Elasticity, Hooke's Law, Oscillation, SHM Notes -** I teach Hooke's Law during Energy. Oscillations & SHM I teach together right before sound. Here are my notes from both. They are modified from //Physics, Algebra/Trig, Hecht//. Only good for AP B. [[file:Chapter 10 - Elasticity & Oscillations.pdf]] //Contributed: Mark W. Hossler//, mhossler@landmark-cs.org


 * 4. Fluids & Oscillators Notes**: //Donated from Wayne Mullins.// [|Click here to check them out].

This lab deals with a cart attached to two fixed springs and it oscillates back and forth. They find an "effective spring constant" through plotting data and then, hopefully, derive the effective spring constant through a force diagram to get (-k1x-k2x)=md^2x/dt^2.
 * 5. Oscillator Lab with Multiple Springs**. Posted by Brendan Crowley. [[file:Oscillations.doc]]


 * 6. Pendulums** - [[file:13 - Pendulums (2 page).doc]] - Factors which affect the period of a pendulum. I do this before my lecture on pendulums. My students tend not to forget things they figure out for themselves or find surprising. //Submitted by: Mark W. Hossler, mhossler@landmark-cs.org//

//7.// **SHM Kinematics** Vertical Mass on a spring kinematics lab. Data is collected from a oscillating mass on a spring hanging from a force probe over a motion sensor. Based on the Force and Motion labs created at Tufts in the 1980s. I used to do this lab with Apple IIs. Now it is Data Studio. //Submitted by Dan Burns// //8.// **Pendulum Lab** Basic pendulum lab. Students investigate what affects period, then create a pendulum with a 1 second period. Worth downloading just to get the FoxTrot Pendulum Lab Cartoon. //Submitted by Dan Burns //

9. **Physical Pendulum Lab** Uses a meter stick as a physical pendulum for AP Physics C. Students time period for at least five different pivot points and use a graph to find g. //Submitted by Tom O'Dell, todell@hpreg.org//


 * 10. SHM Example Problem Powerpoint Slides** I used these to create screencasts that I post on Youtube for my students. They are meant for students that miss class or want to see additional examples. Some are follow-up examples to labs and demos done in class. You could use them to show in class or to create your own screencasts with your own voice for your students to hear. Feel free to modify them as you wish. Attribution to me is not necessary but please send me any errors you notice or other comments that might improve them. Dan Burns (dburns@lgsuhsd.org)




 * 11.** AP Physics 1 Oscillations Problem Set - **Problem set** built by Bob Enck, Dan Fullerton and Paul Sedita in an effort to start an AP-1 style problem bank. Feel free to print/use in your classrooms. Please don't re-post the files themselves, but rather only the links to the files, to allow us to quickly and easy update and continue to build upon these problems. Thank you! -- Dan Fullerton (dfullerton@aplusphysics.com). PS - anyone interested in adding on to these problems, we'd love the help!

12. **Excel Model of Large Angle Pendulum** - I used 10,000 iterations to model a large angle pendulum. Using Excel to numerically model a problem is fun. [|Large Angle Pendulum Excel Simulation] //Submitted by Dan Hosey//
