Description
Technical field
The present invention relates to a kind of experimental facilities, more particularly to a kind of physics teaching experiment with falling objects equipment.
Background technology
Experiment with falling objects is learned, mainly allows student to understand that the speed of the object fall of different quality under vacuum conditions is
Identical, and during this section knowledge is learnt, if teacher is merely by the teaching of theoretical property, then except teaching side
Formula it is uninteresting beyond, simultaneously because this section knowledge of freely falling body is originally just relatively abstract, if not focusing on allowing student personally to know from experience,
It is extremely difficult to teaching purpose.
Therefore, a kind of physics teaching experiment with falling objects that knowledge vivo can be communicated to student of research and development is needed badly to set
It is standby.
The content of the invention
(1) technical problems to be solved
The present invention in order to overcome sees freely falling body theoretical abstraction, the shortcomings that student's indigestion, the invention solves skill
Art problem is to provide a kind of physics teaching experiment with falling objects equipment that knowledge vivo can be communicated to student.
(2) technical scheme
In order to solve the above-mentioned technical problem, the invention provides such a physics teaching experiment with falling objects equipment, bag
Casing, installing plate, vavuum pump, through hole, plug, handle, framework, sealing shroud, baffle plate, pull bar and the first spring are included, casing is right
The outer side-lower of wall is provided with installing plate, and vavuum pump is provided with above installing plate, and vavuum pump is connected by pipeline with lower section on the left of casing, case
Body left wall is provided with through hole, and movable type is provided with plug in through hole, and symmetrical above and below be provided with is shaken hands on the left of plug, below casing upper wall or so
It is arranged with framework, is provided with sealing shroud at left and right sides of casing upper wall, movable type is provided with baffle plate in sealing shroud, and two baffle plates are respectively with two
Framework is contacted, and two baffle plate upper ends are connected with pull bar, symmetrical on the downside of pull bar to be provided with the first spring, the first lower spring end and casing
Upper wall connects.
Preferably, also include second spring, baffle plate, button and bulb, bottom half respectively with four second springs
End connection, two, left side second spring upper end are connected with left side pressing plate, and two, right side second spring upper end is connected with right side pressing plate,
Button is equipped with immediately below two pressing plates, bottom half is connected with button bottom, and top is provided with two bulbs on the outside of casing right wall, on
Square bulb is connected with left side button by electric wire, and lower bulb is connected with right-hand button by electric wire.
Preferably, air inlet pipe and valve are also included, top is provided with air inlet pipe on the outside of casing right wall, and air inlet pipe is provided with valve
Door.
Operation principle：Just, teacher is taken away plug by shaking hands from through hole, and then teacher pulls up pull bar for experiment,
First spring is stretched, and pull bar drives baffle plate to move up, and baffle plate is not closed again framework, and now, teacher will distinguish in two frameworks
The object A and B, A that load unlike material weight are 2 times of weight of B, teacher's releasing lever, work of the pull bar in the first spring
Moved down with lower drive baffle plate, baffle plate closes framework again, and now the object in framework can not fall, and teacher is again by drawing
Hand gets back into plug in through hole, pulls up pull bar, and the first spring is stretched, and pull bar drives baffle plate to move up, and baffle plate is no longer
Framework is closed, is fallen simultaneously because losing the effect of baffle plate so as to object A and object B, due to being and A weight in atmosphere
Amount is twice of B weights again, so A takes away plug again by shaking hands prior to B to bottom half, teacher from through hole, then
Teacher pulls up pull bar, and the first spring is stretched, and pull bar drives baffle plate to move up, and baffle plate is not closed again framework, from casing
Object A and object B is taken out in bottom, two articles is put back into respectively in the position of framework script, teacher is by shaking hands plug plug
Return in through hole, teacher starts vavuum pump, and vavuum pump drains the air in casing, and now, teacher again pulls up pull bar, draws
Bar drives baffle plate to move up so that the object fall in framework, although A weight is twice of B, casing is now arranged in
Vacuum state, during freely falling body.A and B falls on bottom half simultaneously, and freely falling body theory is clearly confirmed.
Because also including second spring, baffle plate, button and bulb, bottom half connects with four second spring lower ends respectively
Connect, two, left side second spring upper end is connected with left side pressing plate, and two, right side second spring upper end is connected with right side pressing plate, pressing plate
Be arranged right below button, bottom half is connected with button bottom, and top is provided with two bulbs on the outside of casing right wall, upper bulb and
Left side button is connected by electric wire, and lower bulb is connected with right-hand button by electric wire, when A, B two articles whereabouts, is just fallen
On left pressing plate and right pressing plate, second spring is compressed, and left pressing plate and right pressing plate depress left button and right button under force,
So as to light two bulbs, the time order and function that people can be lit according to upper and lower bulb sequentially judges that object successively falls suitable
Sequence so that experimental result becomes apparent from understanding.
Because also including air inlet pipe and valve, top is provided with air inlet pipe on the outside of casing right wall, and the air inlet pipe mouth of pipe is portable
Provided with valve, when experiment finishes, teacher can be by pulling up valve, so that air is filled out along air inlet pipe into casing
Air is filled, after full air is filled in casing, teacher moves down valve air inlet pipe and is closed, and then teacher easily can
To open plug by shaking hands.
(3) beneficial effect
Invention achieves the effect that knowledge vivo can be communicated to student, and the present invention is by installing air inlet pipe and valve
The mode of door so that the casing drained in experimentation is opened more easily by air inlet pipe air inlet after experiment
Thing in plug taking-up, so that next time uses the equipment.
