This is a software simulation of a lab where the motion of a toy tractor or other object is measured with the use of a ticker or spark timer. The students run the simulation and the resulting dots can be printed out. There are two "runs", Run #1 where the velocity is a constant and Run #2 where the acceleration is a constant. The velocities and accelerations are chosen randomly within a range so each lab group should have different values.
A coded number is included on bottom right of the printouts that you can use to calculate the constant velocity or acceleration.
A lab handout is included which has students graph distance versus time and velocity versus time for each run or motion. They then must straighten out any curve and find the equation for every straight line.
The directions, a description of the real world equipment, and how the data will be analyzed is included in the software simulation. You can have students use this or project it on a screen for use in front of the class.
Two Excel spreadsheets are included with sample data and graphs for a constant velocity and constant acceleration printout.
At the end of the lab handout, there are a series of questions that summarize the shapes of the curves for each run and lead students to find the actual acceleration.
The files are all included in a zip file listed as follows:
Software Simulation: TickerTimerLab.exe
Lab Handout: TickerTimerLab.doc / TickerTimerLab_Key.doc
Excel Constant Velocity: TickerTimer_v=k.xlsx
Excel Constant Acceleration: TickerTimer_a=k.xlsx
The files are downloaded in a Zip file. Unzip and double click on the executable file (.exe) to run the software.
Requirements: PC with Windows XP or later
