Model No. ME-6810 Time of Flight Accessory Introduction The PASCO ME-6810 Time-of-Flight Accessory is for use with PASCO Projectile Launchers. It consists of a piezo-electric speaker circuit mounted on a 20 x 20 centimeter plastic plate. The plate has a signal cable with a 6 mm (1/4”) stereo phone plug. When a ball hits the plate, the speaker circuit generates a Photogate-like pulse. The cable sends the signal to a timer.

Time of Flight Accessory Model No. ME-6810 Setup the Time of Flight Accessory with a Photogate Timer a) Setup for a Time of Flight Study (with Timer) Equipment Requirements: See page 4 of this manual. 1. Remove the Photogate Head from the support rod of the Photogate Timer. 2. Put the Photogate Mounting Bracket onto the Projectile Launcher. Mount the Photogate Head at the front of the Launcher.

Model No. ME-6810 Time of Flight Accessory 4. Connect the stereo plug of the first photogate into the Timer. Set the Photogate Timer to PULSE mode to measure the time of the projectile from the first photogate to the second photogate. 5. Connect the stereo plug of the Time of Flight Accessory into a second timer or a Smart Timer (ME-8930). (Note: If you do not wish to measure time of flight, skip this step.

Time of Flight Accessory Model No. ME-6810 4. Connect the Time-of-Flight Accessory into the computer interface using the extender cable. 5. Run the timing program and set it to measure the time between the blocking of two photogates (one Photogate and the timer plate of the Time-of-Flight Accessory). Procedure: 1. Put the plastic ball into the Projectile Launcher and cock it to the short range position. 2. Test fire the ball to determine where to place the timer plate on the floor.

Time of Flight Accessory Model No. ME-6810 4. Connect the Time-of-Flight Accessory to the computer interface using the extender cable. 5. Run the timing program and set it to measure the time between the three successive signals (two Photogates and the timer plate of the Time-of-Flight Accessory). Procedure: 1. Put the plastic ball into the Projectile Launcher and cock it. 2. Test fire the ball to determine where to place the timer plate on the floor. Put the timer plate on the floor where the ball hit.

Use the extender cable if necessary. 5. Run the timing program and set it to measure the time between blocking of two Photogates (one Photogate and the timer plate of the Time-of-Flight Accessory). 6. Set up the vertical target board about 0.5 m in front of the Projectile Launcher.

Time of Flight Accessory Model No. ME-6810 Teacher’s Guide Experiment 1: The Relationship between Time of Flight and Initial Velocity Notes on Setup: 2. It is important to keep the launcher exactly horizontal. Use a spirit level for best results. 3, 4. You may use one of several timing options for this experiment. Consult the manual for your computer interface, and then connect things so that the Photogate starts the timer and the timer plate of the Time-of-Flight Accessory stops it.

Model No. ME-6810 Time of Flight Accessory 4. The initial velocity should be close to that measured in other experiments (See manual experiments 1 and 2, for example.) 6. The difference should be less than 5%. Experiment 3: Horizontal Velocity of a Projectile Notes on Setup: 3-5. If necessary, consult your interface manual. The system should be set up in such a way that the computer measures the time between the Photogate and the timer plate. 6.

Time of Flight Accessory Model No. ME-6810 Appendix A: DataStudio Software Instructions for Using the Time of Flight Accessory with a PASPORT Interface Instructions for an Initial Velocity and/or Time of Flight Study 1. Connect the photogate and time of flight accessory stereo plugs to the Photogate Ports. [Note: You will need 1-2 photogates and 1-2 PASPORT Photogate Ports (PS-2123). See the PASPORT interface Note: To change measetup instructions on page 7 of this manual.] 2.

An icon for the timed entry will appear in the Data List. 11. For an initial speed and time of flight study: You will need to create two timers for this experiment: one timer for “Time between Gates” and a second timer for “Time of Flight”).
