Velocity with a single gate:
Velocity with a single gate is the very basic velocity
measurement using only one photo gate sensor and
any object with a known width.
1.
Click the “Experiment Setup” button in the Edu-
logger software and select “Velocity with a single
gate”.
2.
The graphic demonstrates the basic idea of what
your experimental setup should look like.
3.
Measure and input the object width (in
millimeters) into the text field labeled “X[mm]”
4.
Click “Save” and then you are ready to begin
data collection.
Velocity with two gates:
The velocity with two gates option is ideal for
experiments which examine collisions between two
objects of known width and mass.
1.
Click the “Experiment Setup” button in the Edu-
logger software and select “Velocity with two
gates”.
2.
The graphic demonstrates the basic idea of what
your experimental setup should look like.
3.
Measure and input the width and mass for both of
the objects passing through the photo gate.
4.
Assign each of your photo gate sensors to both
the “Sensor A” and “Sensor B” position.
5.
Be sure to space the photo gates far enough apart
to allow for a collision between the two objects
before they rebound back through the photo
gates.

Click “Save” and then you are ready to begin
data collection
