Physics 2015 – Introduction to Motion PURPOSE Analyze your own motion using a motion sensor to learn about the following: Position-time graphs Velocity-time graphs The relationship between both graphs The relationship between the shapes of these two graphs to how the objects move Department of Physics & AstronomyPage 2

Physics 2015 – Introduction to Motion EQUIPMENT Department of Physics & Astronomy Logging in and out of lab computers Log in as “labuser” (no password necessary) Log out at the end of your lab, but leave the computer on. Pasco 750 Interface Leave these interfaces “on” (green light at the front is on). Page 3

Physics 2015 – Introduction to Motion EQUIPMENT Department of Physics & Astronomy Motion Sensor Both plugs go into the 750 Interface – yellow into port 1, and the black into port 2 The slide switch has two settings (wide and narrow angle detection); the wide angle works best Software – Capstone You can open the Capstone activity from the website. Open today’s lab activity, “Introduction to Motion.cap” Page 4

Physics 2015 – Introduction to Motion HINTS Department of Physics & Astronomy Hints for Getting Good Graphs Hold a lab manual or book in front of your chest while moving. This creates a flat surface for the sound coming from the detector to bounce off of. Be sure you have enough room to move around! To do this, you may need to aim your sensor into the middle of the room, or into a corner. Please don’t aim your sensor into another group either! Use the Capstone tools to rescale your graph axes or to read out data points. Page 5

Physics 2015 – Introduction to Motion GENERAL CLASS POLICIES Homework Policies You must do your homework BEFORE CLASS, and everyone must turn in their own work. Lab Report Policies Submit one lab report per group. Groups should generally consist of two people maximum, three if necessary due to over enrollment. Make sure both members of the group write their name on the lab report! Department of Physics & AstronomyPage 6
