Abstract
The invention provides an auxiliary device for a physical experiment, solves the problem that the initial speed of the collision of a momentum conservation experiment is not horizontal, avoids adverseinfluence on an experiment result and lowers interference, caused by human factors, to the experiment. According to the technical scheme, the auxiliary device comprises a flat plate and is characterized in that a left vertical plate and a right vertical plate are arranged at two ends of the flat plate, the left vertical plate is provided with a first vertical plate and a second vertical plate, the second vertical plate is provided with a first rack, pinions are arranged in the front and at the rear of the first rack, second racks are arranged on one sides of the pinions, a third rack is arranged on the first rack, the pinions are provided with pins, a slide plate is arranged between the second rack and the second vertical plate, the slide plate is provided with a first positioning pin anda second positioning pin, a bull gear is arranged on the third rack, and a counter weight is arranged below the bull gear. The auxiliary device is novel in concept, ingenious in structure, capable ofguaranteeing that the initial speed of a small ball in the momentum conservation experiment is horizontal, capable of reducing influence, caused by the human factors, on the experiment, capable of lowering the leveling difficulty of the experiment, capable of facilitating operation by staff, high in practicality and easy to popularize.
Description
technical field [0001] The invention relates to the technical field of auxiliary devices for high school physics experiment instruments, in particular to auxiliary devices for physical experiments. Background technique [0002] The energy conservation experiments learned in high school usually refer to experiments in one-dimensional situations, that is to say, to maintain a horizontal initial velocity. At present, the experimental equipment used in high schools to verify the conservation of momentum uses small balls that roll down an inclined rail. To verify the law of conservation of momentum by colliding with a ball at rest on a horizontal orbit. The experiment requires that the colliding ball and the collided ball be ejected from the horizontal track, which requires the instrument to be horizontal. However, existing experimental instruments do not have the function of adjusting the level. If the experimental table is not level, the ball will not be thrown flat in the ai...
