The invention discloses a freefall and horizontal projectile motion experimental instrument, which comprises a base, supporting legs, gaskets, adjusting knobs, sliding rods, an experimental board, fixing knobs, a ball net, a horizontal projectile motion chute, a support rod, a stop rod, steel balls, fixing clamps, an elastic rod, and freefall clamping rods. The support legs are installed beneath the base. The gaskets are arranged beneath the support legs. The adjusting knobs are respectively arranged at the left and right sides of the base. The sliding rods and the experimental board are installed on the base. The sliding rods are connected with the ball net through the fixing knobs respectively. The horizontal projectile motion chute is arranged at the left side of the experimental board. The support rod is installed beneath the horizontal projectile motion chute. The stop rod is arranged on the horizontal projectile motion chute. One steel ball is placed at the left side of the stop rod. With the freefall and horizontal projectile motion experimental instrument, the motion trajectory of a horizontal projectile can be depicted accurately, and the initial velocity of the horizontal projectile can be calculated. Both horizontal projectile motion experiment and freefall experiment can be conducted. Moreover, the freefall horizontal projectile motion experimental instrument is simple in structure, convenient to operate, and conducive to student experiment in group.
Description
technical field [0001] The invention relates to an experimental instrument, in particular to an experimental instrument for free-falling flat throwing motion. Background technique [0002] Experiments occupy an important position in high school physics teaching. At the same time, experiments are also the standard for testing the truth of physics. The experiment of free fall and flat throwing is a relatively important experiment in high school physics teaching. students' hands-on ability. The flat-throwing motion experiment apparatus used at present can only realize the flat-throwing motion experiment, but cannot realize the free-fall experiment, has a single function, is inconvenient to operate, and is not very conducive to the group experiment of students. Contents of the invention [0003] The object of the present invention is to provide a free-fall flat throwing tester to solve the problems raised in the above-mentioned background technology. [0004] In order to ach...
