Apparatus Based Experimental Study of Physics Phenomena

Basic measurement concepts of a new apparatus for the experimental study of physics phenomena based on laser modules and detectors are presented in this paper. Construction details of the proposed apparatus are also described. Measurement time base is 100 musec (depending on the microprocessor used) and in each cycle, data coming from eight photo-detectors are stored. When an experiment is finished or corrupted by a user, data are transferred in a personal computer and with the aid of a software application (depending on the experiments) final values of variables are calculated. The results as well as graphical representations of them are displayed on the screen. The proposed apparatus can be used to study straight or circular movements with controlled friction or without friction, collisions, gravitation phenomena, to measure acceleration of gravity (g), reflection and refraction phenomena as well as to permit in a pupil or student to be experimented with digital gates
