The utility model has the advantages of rational structure, convenient operation, clear dotting, good experimental effect, and functions of three experiments, such as verification of conservation of mechanical energy, the research of Galilean falling body motion, (the heavy ball and the light ball simultaneously fall to the ground) and the detection of the human reaction time with the time ruler, etc.
Description
Technical field
The utility model relates to a kind of middle school experiment utensil, and is especially relevant with the falling tester.
Background technology
In middle school physical curriculum, there are many Experiments of Machanics to do, as the research of the movement of falling object, checking conservation of mechanical energy etc.But in the experiment of checking conservation of mechanical energy, feel that experiment effect is undesirable, error is big between measurements and calculations value and the theoretical numerical value.The existing experimental provision that uses, its electromagnetic shooting point timer vertically is fixed on the iron stand, and weight is suspended on the paper tape, and paper tape will pass the pilot hole and the copy paper of dotted timer.During experiment, with portable paper tape, energized then, letting go allows the weight free-falling, requires timer to lay a series of points on paper tape, and to pick out the 1st and the 2nd between distance be about 2 millimeters paper tape and carry out measurements and calculations.Because the shake of hand, the friction between paper tape and the timer adds the deficiency that electromagnetic shooting point timer itself exists, and it is just difficult to select the clear qualified again paper tape of a mark.Even, when experiment weight can take place also forget about it iron stand, break the phenomenon of dotted timer.In addition, above-mentioned experimental provision can't carry out Galileo falling research that requires in the newly organized physics teaching material and the experiment of measuring people's reaction time with short chi.
Summary of the invention
The purpose of this utility model provides a kind of rational in infrastructure, and is easy to operate, and experiment effect is good and have the checking conservation of mechanical energy concurrently, the Galileo falling is studied and measure the multi-functional falling tester of reaction time three kinds of experiential functions of people with short chi.
For achieving the above object, the utility model is achieved through the following technical solutions.Multi-functional falling tester comprises base, fixed support, the support platen, dotted timer, control panel, telescopic lever, time ruler, operation circuit and paper tape, spacing hole on the dotted timer is located on the support platen, paper tape is attached on the time ruler and passes spacing hole together, also is provided with iron plate on time ruler top, and control panel is by panel, electromagnet and pilot lamp constitute, and electromagnet and pilot lamp are connected with toggle switch and keyswitch by operation circuit.
Described multi-functional falling tester, its dotted timer is by base plate, and solenoid vibrates sheet metal, limited bolt, get water-color paintbrush ready, commutation diode and power-line terminal are formed, and vibration sheet metal one end is fixed, water-color paintbrush is got in other end setting ready, solenoid is connected with commutation diode, and solenoid and limited bolt are located on the base plate and are being vibrated the sheet metal stiff end and getting ready between the water-color paintbrush, and power-line terminal is located on the base plate.
The utility model compared with prior art has the following advantages: (one) is the reaction time three kinds of experiments that can verify conservation of mechanical energy, Galileo falling research simultaneously and measure the people with short chi; (2) be reasonable in design, easy to operate, experiment effect is good, and experimental data is accurate.
