The experiment in studying Physics


The experiment is a method of exploring the reality
directly, used largely in teaching Physics by observation
provoked and guided by certain hypotheses which are
to be verified by experiments.
The experiment is the didactic method which puts
students in the situation of provoking intentionally a
process or a physical phenomenon, or of modifying the
normal conditions in which these are to take place by
introducing new variables so that all of these are to be
studied further.

Data acquisition systems
Data acquisition means the sampling and the scanning of the
real world in order to register data that can be manipulated
by a computer. The components of data acquisition systems
include appropriate sensors that convert any analogical
signal to an electrical signal, then conditioning the electrical
signal which can then be acquired by data acquisition
hardware.
