Go! Motion
(Order Code GO-MOT)
Go! Motion is used to collect position, velocity and
acceleration data of moving objects. Go! Motion's USB port
allows for direct connection to a computer's USB port, which
simplifies experiment set up. Students can study a variety of
motions with Go! Motion, including
•
Walking toward and away from Go! Motion.
•
Dynamics carts moving on track.
•
Objects in simple harmonic motion, such as a mass hanging on a spring.
•
Pendulum motions.
•
Objects tossed upward or dropped.
•
A bouncing object.

What is Included with Go! Motion?
Go! Motion ships with the detector, a USB cable that
connects Go! Motion to a standard USB port, and a CD
containing Logger Lite software. These materials are
everything that you need to use Go! Motion with a USB-
compatible computer.
Quick Start Guide
To get started on a computer right away, follow these easy steps.
1. Install the Logger Lite software.
2. Connect the square end of the USB cable to the USB port on the left side of
Go! Motion.
3. Connect the other end of the cable to a USB port on your computer.
4. Start Logger Lite, and you are ready to collect data. Note: Go! Motion can also be
used with Logger Pro software.
How Go! Motion Works
This Motion Detector emits short bursts of ultrasonic sound waves from the gold foil
of the transducer. These waves fill a cone-shaped area about 15 to 20° off the axis of
the centerline of the beam. Go! Motion then "listens" for the echo of these ultrasonic
waves returning to it. The equipment measures how long it takes for the ultrasonic
waves to make the trip from Go! Motion to an object and back. Using this time and
the speed of sound in air, the distance to the nearest object is determined.
Note that Go! Motion will report the distance to the
closest object that produces a sufficiently strong
echo. Go! Motion can pick up objects such as
chairs and tables in the cone of ultrasound.
The sensitivity of the echo detection circuitry
automatically increases, in steps, every few
milliseconds as the ultrasound travels out and back.
This change in sensitivity enables the detection of weaker signals.
Features of Go! Motion
•
Go! Motion is capable of measuring objects as
close as 0.15 m and as far away as 6 m. The
short minimum target distance allows objects
to get close to the detector, which reduces
stray reflections.
