EQUIPMENT FOR STUDYING FREE FALL AND ATWOOD S MACHINE.
EQUIPMENT FOR STUDYING FREE FALL AND ATWOOD S MACHINE Displaying the phenomenology of the free fall of a body is
always difficult because time intervals and covered distances
are short. This equipment is designed for the teaching of this
topic in two phases: Atwood’s machine and free fall.
Atwood’s machine enables to study the fall of a body subject
to a constant force, but at low speed so that friction of the
air is negligible. This characteristics allows to appreciate
the phenomenology concerning free fall, even visually. This
apparatus consists of a vertical stand of aluminum where
the various system configurations can easily be assembled. A
complete set of tests can be carried out.
Uniformly accelerated motion, fall with viscous friction,
oscillatory motions in fluids, oscillatory motions with constant
forces can be studied. The notions learnt with the first
configuration enable students to carry out a classical test of
free fall, with the second configuration, besides determining
the acceleration of gravity and assessing the effects of the air
on motion.
All system parameters (velocity, forces, accelerations) can be
acquired via datalogger and proper sensors. Furthermore,
the equipment also includes a specific software that enables
to carry out all the tests simply and to compare theoretical
hypotheses wit experimental measures, besides displaying the
motions examined, on charts and tables, in real time.
