1- Author, Paul Lulai plulai@stanthony.k12.mn.us 2- Lab Type: Structured, Engineering 3- Students use a force sensor and motion detector. The measure force of tension on a material (for me, printer ribbon or very lightweight fishing line) and the elongation of the material. A graph of the materials properties is produced. It plots Stress (force / area of material) vs Strain (elongation / original length). A materials Young's Modulus and maximum tensile strength can be measured. My students then use this data to determine how many loops of the material they need to hold up a lab-mate. 1. Author: Brittany Reed brittany_reed@bullis.org 2. Lab type: Inquiry/investigation 3. I use this lab on one of the first days that I begin talking about forces and different types of forces. Students investigate how Normal, Friction, and tension forces change in different situations.

 * Flying Pig Centripetal Force** [[file:farming-flying-pigs.doc]]
 * 1) Author: Paul Lulai plulai@stanthony.k12.mn.us
 * 2) Lab Type: Inquiry/Problem Solving
 * 3) Students determine the minimum tensile strength required for a leash to be used on flying pigs. Students also find net radial F (aka centripetal), net radial acceleration, tangential velocity, angular speed and so on.


 * Flying Pig Force Vectors[[file:FlyingPig.pdf]]**
 * 1) Author: Paul Robinson (posted by Chris Becke)
 * 2) Lab Type: Guided problem solving
 * 3) Students are led through splitting the tension into x- and y-components and compare a theoretical velocity to a measured velocity. Honors level or AP B level.


 * Flying Pig Canonical Pendulum** [[file:Flying Pig Canonical Pendulum.doc]]
 * 1) Author: Bill Taylor, bt4_1284@yahoo.com
 * 2) A toy flying pig is a canonical pendulum. By measuring the mass of the pig and the radius of the pendulum, one can determine the (theoretical) equilibrium speed of the pig. This can be compared to the actual speed. I use this Lab in AP-C, but it could also be used in an Honors course.

This is a pretty straight-forward lab that uses the rotational apparatus from Pasco, but could be easily modified, and the goal is to determine the rotational inertia for a variety of objects.

 * Equilibrium & Torques** If you are a risk taker, give the following web site with no instructions other than to turn in a drawing or printout of the end. Tell them they will know when the end happens. I've done this two years in a row.

//Suggested by Helen Young; Posted by Bill Taylor//
 * Equilibrium & Torques** I give my students a meter stick, a loop of light string with which to suspend it from a pole stand, a standard mass (200 grams works well) and another loop of string to use in suspending that from the meter stick. The task: determine the mass of the meter stick. I let the kids check their result with a balance scale after they have finished their calculations. Usually, they find the task hard and do much more complicated calculations than are needed!

 * Rotating Beam and Center of Mass 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)



AP Physics 1 Dynamics 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!

LAB - Determining the Coefficient of Friction between two materials using video analysis:


 * Static Beam Lab**: Students predict the tension for a horizontal beam supporting a weight and then for when the beam is at an angle to the horizontal. A force sensor allows them to test their prediction. Below is a picture of the beams in both configurations. - Dan Burns[[file:Static Beam Lab.docx]]

Students use F=kx to find spring constant without knowing actual x, find length of spring, find unknown mass, then g on Planet X. Good practice for Hooke's Law. - Dan Burns
