The Research foundation of other each natural branch of sciences.Its theoretical construct makes full use of mathematics as the working language of oneself, with
As the sole criterion of inspection theoretical correctness, it is a most accurate now natural science subject for experiment.
Only under gravity, initial velocity is zero motion to conventional object, is called the movement of falling object.Freely falling body is transported
Dynamic is a kind of physical model ideally.Be any object under gravity, at least initial, only gravity is only
Produce inertial track under the conditions of one strength, be the uniformly accelerated motion that initial velocity is 0.Because this defines the side of not clear and definite initial velocity
To it is also applied for object and initially moves up.Because beyond atmosphere in the case of free-falling, gravity produces weightlessness, sometimes
Any weightless state is referred to as freely falling body due to inertia motion.This may be also applied for weightless generation and be because body away from drawing
Power body.Although the object that the definition of strict technology application does not include moving is subject to other resistances, such as air drag, in non-technical
Usage, the parachute that can not disposed by atmosphere, or hoisting apparatus, also commonly known as freely falling body.Resistance is in this situation
Under, prevent them from producing complete agravity state, thus " freely falling body " of parachute jumping incoming terminal speed sensigenouses body afterwards
Weight is to support in an air cushion.
The movement of falling object comes from centrifugal force, and object starts whereabouts from geo-stationary under only by action of gravity and moved
It is called the movement of falling object (its initial velocity is vo=0m/s) and such as grasps certain object, do not apply the ideal of any external force
Under the conditions of gently unclamp the physical phenomenon occurring after handss.
Existing free fall experimental device haves the shortcomings that complex structure, complex operation, experiment effect are poor, therefore needs badly
Research and develop the student that a kind of structure is simple, easy and simple to handle, experiment effect is good and use high school physicses free fall experimental device.
Utility model content
(1) technical problem to be solved

Shortcoming, the technical problems to be solved in the utility model is to provide a kind of structure is simple, easy and simple to handle, experiment effect is good student
Use high school physicses free fall experimental device.
(2) technical scheme
In order to solve above-mentioned technical problem, it is real with high school physicses freely falling body that this utility model provides such a student
Experiment device, include bracing wire, bracing wire, electronic reel, bracing wire, support, cylinder, electric magnet, iron hoop, cavity, flexible pipe,
Air pump and pole；Top left side in support is provided with bracing wire and bracing wire, and bracing wire is located at the left side of bracing wire, in support
Top below be provided with cavity, the lower end of bracing wire is connected with the left wall bottom of cavity, the left wall top of the lower end of bracing wire and cavity
End connects, and the top right side in support is provided with electronic reel, and electronic reel is wound with bracing wire, and the bottom of bracing wire connects
There is iron hoop, the right wall in support is provided with cylinder, and the left side of cylinder is connected with electric magnet, and electric magnet is located at the positive right side of iron hoop
Side, the bottom of the left inside wall of support is provided with pole, and the top of pole is provided with air pump, is connected with soft between air pump and the left wall of cavity
Pipe.
Operation principle: cavity is transparent, and cavity is built with feather and stone, when student need to do freely falling body real
When testing, iron hoop is made to entangle cavity first, feather and stone are located at the high order end of cavity.Then start cylinder elongation, drive electromagnetism
Ferrum is moved to the left, and when electric magnet moves to suitable position, cylinder stops elongation, and electric magnet is energized, and so that electric magnet is inhaled
Live iron hoop, then start cylinders retract, electronic reel rotates clockwise, and bracing wire is released simultaneously, when iron hoop departs from cavity
When, cavity just inclined downward to the left, last cavity is vertical state in the presence of bracing wire and bracing wire, and student just can be seen that
Stone first drops down onto the right inwall of cavity, drops down onto the right inwall of cavity after feather.Then to electric magnet power-off, start electronic coiling
Wheel rotates counterclockwise, and bracing wire is withdrawn, and makes iron hoop again entangle cavity, restarts air pump and starts working, and air pump is by cavity
Air extract out, when cavity is evacuated, air pump quits work, and then operates ibid, and last student just can be seen that feather
Drop down onto the right inwall of cavity with stone in synchronization.So can make that student is convenient intuitively to experience the movement of falling object.
(3) beneficial effect
This utility model has reached the effect that structure is simple, easy and simple to handle, experiment effect is good.
