Novel centripetal force quantitative measurement experiment instrument

Abstract

The invention relates to a novel centripetal force quantitative measurement experiment instrument, comprising an experimental platform and periphery fixing frame, leveling support legs, side support walls of an experiment instrument body, an experiment instrument platform, an experiment instrument supporting upper beam, a circular small motor, an electric cabinet, a rotary disc, a spring system for measuring centripetal force, a horizontal scale bar and a sliding block, wherein the experiment instrument body is provided with the experimental platform and periphery fixing frame; experiment instrument repair accessory storage drawers are arranged under the experiment instrument platform; the leveling support legs are arranged at the bottom of the experiment instrument platform; the left andright side support walls of the experiment instrument body are respectively arranged at the two sides of the experiment instrument platform; the experiment instrument supporting upper beam is arrangedat the top ends of the side support walls of the experiment instrument body. The novel centripetal force quantitative measurement experiment instrument has the beneficial effects that due to the selected inner side materials of the rotary disc, the sliding block and the horizontal scale bar as well as manufacturing processes of the inner side materials, the friction between the sliding block andthe surface of the rotary disc as well as between the sliding block and the inner side of the horizontal scale bar is very small, that is to say, in a rotating process of the rotary disc, the slidingblock is only under the action of one centrifugal force when relatively sliding on the rotary disc.

Description

technical field [0001] The patent of the present invention relates to an experimental instrument, in particular to a novel experimental instrument for quantitative measurement of centripetal force. Background technique [0002] Centripetal force is an important concept in high school physics and college physics mechanics. The magnitude of centripetal force is related to the mass of the object, the angular velocity (or period) of the rotating object, and the distance from the object to the axis of rotation. It is well known that the centripetal force of an object in uniform circular motion is proportional to the mass of the object, proportional to the square of the angular velocity of the object (inversely proportional to the square of the period), and proportional to the distance from the object to the rotating shaft; There are only experimental instruments for the qualitative demonstration of centripetal force in the physics laboratory, and no experimental instrument for ac...
