Instrument assembles and operating procedure:
1, instrument is installed
Fixing on the base 3 with 2 support bars of pole fixed screw 5, flat throwing gun barrel 9, freely falling body gun barrel 10 are respectively penetrated support bar 5 upper end correspondence position, it is fixed on support bar with screw 8, is respectively adopted confinement circle 7,6 about freely falling body, flat throwing gun barrel and again reinforces, as shown in Figure 1；Freely falling body is shot barral of a gun spring 10-32 and flat impelling hit barral of a gun spring 9-42 and overlap respectively and be fixed in back seat freely falling body gun barrel 10 and throw in inside gun barrel 9 with flat, namely spring top is fixed on the gun barrel place flushed with support bar 5 face, collision end freely falling body shooting barral of a gun 10-31 peace impelling being hit barral of a gun 9-41 is respectively charged in gun barrel, by rear flap 10-0, 9-0 covers after flat throwing gun barrel 9 and freely falling body gun barrel 10, and by spring 10-32, 9-42 terminal is connected with bonnet, and hit barral of a gun 9-41 and be spirally connected with freely falling body shooting barral of a gun 10-31 and flat impelling with screw respectively, it is emphasized that barral of a gun bonnet 10-0 is hit in freely falling body barral of a gun bonnet 9-0 and flat impelling is an entirety, rear cap surface is provided with hand draw ring 11, as shown in Figure 1；Freely falling body steel ball 10-1 is hanged between the steel ball contact fulcrum 10-20 and antetheca being clipped in freely falling body steel-ball collision block 10-2, flat throwing steel ball 9-1 is put in level throwing collision slide block 9-3 front end, experiment instrument base is put the firm block 4 of flat parabolic experimental instrument balance。Instrumentation requires: flat steel ball of throwing is on same horizontal plane with freely falling body steel ball barycenter, i.e. h1=h2。As shown in Figure 1。
2, operating procedure
After flat parabolic experimental instrument installs。During experiment, throw steel ball pick-up point one piece of plank of paving, plank upper berth a blank sheet of paper in freely falling body steel ball peace, it repaves a carbon paper。Live freely falling body shooting barral of a gun 10-31 peace impelling with pew and hit barral of a gun 9-41 bonnet hand draw ring 11, bonnet extremely suitable distance is drawn along radial direction, hitting barral of a gun bonnet 10-0 with freely falling body shooting barral of a gun bonnet 9-0 due to flat impelling is an entirety, therefore barral of a gun 9-41 is hit in flat impelling, barral of a gun spring 9-42 and freely falling body shooting barral of a gun 10-31 is hit in flat impelling, freely falling body shooting barral of a gun spring 10-32 is pulled to certain distance simultaneously, freely falling body shooting barral of a gun spring 10-32, flat impelling are hit barral of a gun spring 9-42 and are had bigger elastic potential energy, as shown in Figure 3；Now, bleed off hand draw ring and namely bleed off bonnet 11, under the effect of spring power, flat impelling is hit barral of a gun 9-41 and freely falling body shooting barral of a gun 10-31 and is done accelerated motion, flat impelling is hit barral of a gun 9-41 and freely falling body shooting barral of a gun 10-31 and is collided with level throwing collision slide block 9-3 and freely falling body steel-ball collision block 10-2 respectively, level throwing collision slide block 9-3 clashes into flat throwing steel ball 9-1, the flat steel ball 9-1 that throws makes level throw motion, freely falling body Impactor 10-2 rotates axle 10-21 rotation around freely falling body Impactor 10-2 simultaneously, steel ball contact fulcrum 10-20 is upspring, freely falling body steel ball 10-1 will free-falling, so flat throwing steel ball 9-1 and freely falling body steel ball 10-1 starts simultaneously at and aloft moves, as shown in Figure 4；It is observed that flat steel ball 9-1 and the freely falling body steel ball 10-1 that throws is in motor process, it is in all the time in same level, as shown in Figure 5；Eventually simultaneously fall on carbon paper, thus printing on blank sheet of paper, as shown in Figure 6。
Slide it should be understood that the level throwing collision block slippery fellow 9-31 of design moves in chute 9-2 at level throwing collision block, it is to ensure that level throwing collision block 9-3 can even running, as shown in Figure 6, meanwhile, freely falling body steel-ball collision block 10-2 is knocked, and rotates axle 10-21 around freely falling body Impactor and rotates, freely falling body steel ball 10-1 freely falls, both adopts Impactor, is artificially create the same terms, to ensure that two steel balls start simultaneously at motion。
Fixing and the freely falling body principle of freely falling body steel ball:
Gravity P suffered by freely falling body steel ball 10-11, freely falling body steel ball 10-1 is produced a holding power F by fulcrum 10-21A by freely falling body Impactor 10-21, freely falling body steel ball 10-1 is produced an elastic force F by wall2, then F1With F2Make a concerted effort to be F, due to F and P1Equal in the vertical direction, F=P2, therefore, freely falling body steel ball is in steady statue；During experiment, freely falling body shooting barral of a gun 10-31 is pulled up, shoot under barral of a gun spring 10-32 resilient force at freely falling body, freely falling body shooting barral of a gun 10-31 clashes into freely falling body steel-ball collision block 10-2, freely falling body steel-ball collision block 10-2 rotates axle 10-21A point around freely falling body Impactor and rotates, freely falling body Impactor contacts fulcrum 10-20 and upsprings with steel ball, freely falling body steel ball 10-1 will free-falling, as shown in Figure 4。
Laboratory observation processes with data:
1, observe in the dropping process of flat throwing steel ball and freely falling body steel ball and whether be in same level, and whether land simultaneously；
2, according to experimental procedure, flat throwing steel ball and freely falling body steel ball drop height h are measured1=h2, and the flat horizontal range s (flat throwing steel ball throw point and pick-up point spacing) throwing steel ball flight；
3, according to movement of falling object formula h=1/2gt2, calculate freely falling body fall time
Because h1=h2, therefore flat steel ball horizontal movement speed of throwing is
