Description
Technical field
The utility model relates generally to a kind of physics facility, the demonstrating experiment device that particularly demonstrating level throw motion track is used.
Background technology
In senior middle school physics teaching, level throw motion is focal points, and it belongs to the extension of the composition and decomposition knowledge of motion, and we know and are dished out with certain horizontal initial rate by object, object is in the curvilinear motion being only subject to do under the effect of gravity, and we are referred to as level throw motion.A complicated curvilinear motion as level throw motion, for high school student, want directly analyze curvilinear motion or there is very large difficulty, therefore take to decompose level throw motion, it is decomposed into the movement of falling object on the linear uniform motion of horizontal direction and vertical direction.In order to reach in physics teaching studying rule of horizontal projectile movement, observe flat paraboloid movement locus, resultant motion that checking level throw motion is horizontal forward linear uniform motion and the movement of falling object vertically downward, be designed with multiple test apparatus.
In existing experiment instrument of flat throw movement device, the single bead of many employings realizes level throw motion, these demonstration instruments have very large shortcoming to be exactly that presentation process is too short, the motion process of bead and movement locus can not be presented in face of student clearly, and this understands horizontal projectile motion trajectory to student and movement characteristic is very difficult.Certainly also have can record bead movement locus patented invention, if number of patent application is the patent of 201210063530.1, when utilizing magnetic force steel ball to do level throw motion, magnetic force is through trace graphics plate, the movement locus of the principle record level throw motion object utilizing magnetic attracting, on instrument outside framework, fluting takes out trace graphics plate again, so just can see motion locus of steel ball.The object of track reproducing has been accomplished in this patented invention really, but experimental principle is too complicated, and student is difficult to the principle understood wherein, and this will allow student go to suspect whether this track puts down on earth and throw the real movement locus of bead.For another example number of patent application is the patented invention of 200510111108.9, the selection of projectile have selected water, and select setting angle regulator at shower nozzle place, so just can distinguish demonstrating level throw motion and inclined throw movements by regulating the angle of shower nozzle, although the demonstrating effect of this invention is fine, but for track description but seem pretty troublesome, what this invention adopted in addition is discharge water from a water tank fixed, do not supplement, continuously outflowing so along with current, hydraulic pressure will constantly reduce, the initial velocity that current impelling is gone out will constantly reduce, also corresponding change can be there is in the movement locus of corresponding projectile, therefore carrying out the track experimental error of demonstrating level throw motion with this instrument will be very large, qualitative demonstration can only be done.
Utility model content
The purpose of this utility model is the shortcoming that will overcome known technology, provides an illustrative strong, multi-functional continuation demonstrating instrument of horizontal projectile motion trajectory intuitively.
To achieve these goals, scheme of the present utility model is: multi-functional continuation demonstrating instrument of horizontal projectile motion trajectory, by water tank, water tank one side has multiple nozzle, template, tank is formed, water tank is vertically install, template is vertically fixed on the one side that nozzle installed by water tank, and be arranged on after nozzle, clearly be presented in template as a setting from the para-curve water flow energy of nozzle ejection, template is a flat rectangular box, panel is decorated with coordinate line in length and breadth, rectangular box one is in upper horizontal sides, and adjacent side all has chute, each chute is all provided with a laser pen, at tank built with submersible pump, feed-tank supplies water.
Adopt such scheme, can para-curve forming process that is clear, demonstrating level throw object intuitively, achieve the purpose of this utility model.
Below in conjunction with diagram and embodiment, scheme is described in more detail.
Accompanying drawing explanation
Fig. 1 is multi-functional continuation level throw motion track demonstrator stereographic map.
Illustrate: 1 tank, 2 rubber tubes, 3 submersible pumps, 4 templates, 5 horizontal laser, 6 chutes, 7 organic plates, 8 vertical laser instruments, 9 trajectories, 10 spillway holes, 11 sparge pipes, 12 vertical water tanks, 13 pigment water.
Embodiment
As shown in Figure 1, there is a tank be bonded by poly (methyl methacrylate) plate 1, sink size is designed to 60 × 30 × 25cm, installing one at the left hand edge near tank 1 is the vertical water tank 13 be bonded by poly (methyl methacrylate) plate equally, tank size is designed to 10 × 20 × 60cm, open an aperture on the right side of vertical water tank 13 near the position of bottom and glue a plastic tube in hole, rubber tube 2 one end connects on plastic tube, the other end is connected on the submersible pump 3 bottom tank 1, can provide water source continuously by submersible pump 3 to vertical water tank 12.In the front of vertical water tank 12 close to the position of top 5cm from top to bottom, every 5cm, open three spillway holes 10 successively, for adjusting the height of the water surface in vertical water tank 13 and then regulating irrigation pressure.In the right center position of vertical water tank 12, apart from top 10cm position to top to bottm, every 5cm, horizontal installation length is 3cm, external diameter 1cm successively, the plexi-glass tubular of internal diameter 0.2cm is as sparge pipe 11, and hole for water spraying and spillway hole all will be equipped with corresponding plug.After sparge pipe, vertical installation template 4, template design size is 40 × 60cm, in the upper end of template and right side, Intermediate Gray open slot organic plates 7 is installed respectively, again by laser pen 5,8 are arranged on open slot with wing nut, and laser pen can horizontally slip along open slot and slide up and down to regulate the position of laser pen, conveniently look for a little on projectile motion track, coordinate the coordinate just can determining this point with template.First all spillway holes and sparge pipe are all blocked with corresponding plug during use, then the power switch of submersible pump is opened, pigment water in tank 1 is pumped to vertical water tank 12, when spillway hole close to top of the water surface of vertical water tank, open the spillway hole plug on top, when the spillway hole on top starts outside spilling water time, represent that the liquid level of vertical water tank has remained constant, now open first sparge pipe on top, when water sprays, the water column of ejection is exactly the trajectory of level throw motion, now adjust horizontal laser and vertical laser instrument, make horizontal laser light, when vertical laser and water column three meet at a bit, just can record this some coordinate position now.Due to have spillway hole and submersible pump with the use of, can be good at liquid level in vertical water tank is remained unchanged, horizontal initial rate when this also just ensure that pigment water throwing goes out is always constant.Change the shower nozzle of water spray, shower nozzle is topmost blocked, uses second shower nozzle instead, hydraulic pressure increase is just equivalent to the initial velocity changing projectile like this, the height of the shower nozzle of water outlet can not certainly be changed, and change the height of spillway hole, the object changing projectile initial velocity can be played equally.
