Physics Virtual Laboratory, PVL 1
Physics Virtual Laboratory, PVL - An Intuitively Easy-To-Use collection of -at least- 142 interactive Physics simulation modules that
allow the user to simulate and visualize Physics experiments.
Useful from High School
to University. PVL may be used (1) during classes, to support the teacher's explanation and to make
classes more interesting, (2) in the library by students, to review the topics covered in classes
(3) at home by students to run experiments with the student's data, even extreme experiments, which
result in a better grasping of studied topics. The teacher may also use the PVL to prepare classes
and suggest experiments.
In a conventional (traditional) Physics laboratory it is
impossible to execute experiments with extreme parameters, for instance it is impossible to shot a
gun, because it is dangerous, it is impossible to make changes in the acceleration of gravity, it
is not possible to carry out experiments in "Slow Motion" or to settle a "time freezing". The PVL
overcomes all these drawbacks.
PVL Special Features .-
-Experiment pause (Time
freezing): introducces a pause in the execution of an experiment, usually a pause is used to
display vectors (forces, velocities, etc)
-Slow Motion: executes an experiment slowlyy enough
for the user to appreciate the behaviour of the system.
-Extreme parameters experimentation:
Allowss experimentation with parameters that if used in real life would produce damage to the
equipment or harm the user.
-Visualization of vectors: Usually when thee pause button is
pressed some vectors are displayed. (forces, velocities, accelerations, etc)
Using the
screen as a blackboard.-
In many experiments the user is free to use the screen as a
blackboard, this means that the user may place vectors, blocks, masses, etc wherever he/she wants
on screen, and as many as space allows for. This allows comparative teaching or learning, since
the user is allowed to see several instances of an experiment simultaneously. <>
