3. Measuring Methods
The Timing Wizard offers you various methods of analyzing the different
measurements. In some measurements you will be asked to enter the dimension of
the moving body, or the distance between the two photogates to allow for the
calculation of velocity and acceleration.
The methods depend on the selected measurement:
Time
•
At one gate
Measures the time it takes the
body to cross the photogate
(between blocking and
unblocking the infrared beam).
• Between gates
Measures the time it takes the
body to move from one
photogate to the second
photogate (between blocking
the first and blocking the
second infrared beams).
•
Pendulum
Measures the time period of an
oscillating body (the time
interval between the first and
the third blockings of the
beam).
Velocity
•
At one gate
Measures the time it takes the
body to cross the photogate
(between blocking and
unblocking the infrared beam)
and returns the velocity.
You should enter the body
’ s
width.
