• 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) and
returns the average velocity.
You should enter the distance
between gates.
•
Collisions
Measures the crossing time
intervals at each gate and
returns the corresponding
velocities.
You should enter the bodies
’
width (the width of the two
bodies must be identical)
Acceleration
•
At one gate
A card with two flags must be
attached to the moving body
(see figure to the left). The
Timing Wizard measures the
crossing time intervals of the
two flags and returns the
acceleration.
You should enter the flags
width.
• Between gates
Measures the crossing time at
the first gate, the time it takes
the body to move from one gate
to the second gate and the
crossing time at the second
gate and returns the average
acceleration.
You should enter the body
’ s
width.
