Associated with a passage sensor, the moving ruler makes it possible to accurately determine speed and acceleration during a free fall movement:
Simply position the ruler above the passage sensor and release it.
The sensor then detects the passage of the plexiglass ruler through the regularly spaced black strips (5 cm) on it.
