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. The Time-of-Flight Accessory was designed for use with a PASCO Photogate Timer or a PASCO

computer interface (such as the ScienceWorkshop Interface

or a

PASPORT Photogate Port with USB link) for Macintosh® or

Windows® computers.

Setup Options

The Time of Flight Accessory can be used with a Photogate Timer or a computer interface for time of flight or initial speed studies. If using a computer interface, you will also need data collection software, such as DataStudio. If you plan to measure initial speed and time of flight in the same experiment, you will need two photogates for the setup.

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.

3. Connect the Time-of-

Flight accessory stereo phone plug into the side of the Photogate Timer.

4. Set the Photogate

Timer to PULSE mode to measure the time of flight of the projectile from the launcher to the pad.

b) Setup for an Initial Speed and 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 closest position on the front of the Projectile Launcher. Mount the second photogate at the farthest position on the mounting bracket.

3. Measure the distance between the photogates. You will use this

distance and the measured time between the photogates to calculate the initial speed of the projectile (ball).

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.)

Set up the Time of Flight Accessory with a Computer Interface

You can setup the Time of Flight Accessory for use with a computer

interface and either DataStudio™ or ScienceWorkshop® software.

a) Set up for a Time of Flight Study (with interface)

Equipment Required: 1 Photogate with bracket, 1 ScienceWorkshop interface (CI-6400 or CI-6450) OR 1 PASPORT Photogate Port (PS-

2123) with USB Link (PS-2100) and USB-compatible computer, 1 Time of Flight Accessory, 1 Projectile Launcher, DataStudio software

1. Put the Photogate

Mounting Bracket on to

Projectile Launcher

the Projectile Launcher and mount the photogate at the front of the launcher.

2. For ScienceWorkshop

interfaces: Insert the

Photogate’s stereo phone plug into Digital

2. For ScienceWorkshop

interfaces: Connect the

stereo phone plug from the Photogate that is closest to the projectile launcher into digital channel 1, the stereo phone plug of the second photogate into digital channel 2, and the stereo plug of the Time-of-Flight accessory into digital channel 3 on the interface.

For PASPORT interfaces: Insert the stereo plug of the photogate

into Port 1 on the PASPORT Photogate Port, the stereo plug of the second photogate into Port 2 on the Photogate port, and the Time of Flight Accessory into either Port 1 or Port 2 on a second Photogate Port. Connect each Photogate Port to a USB link and USB port on your computer.

3. Use the computer program that came with your interface to measure

the initial speed and overall time of flight of the projectile from the launcher to the pad (For more information about using a computer program to time the projectile, see Appendices A-C of this manual.)
