Abstract
The utility model proposes centrifugal force demonstration teaching aid.Column chain connection platform on base, platform is provided with the motor placed with plateau levels, the direct-connected rolling disc of axle head of motor, the outer of rolling disc hangs with spring, spring connects counterweight, axle between rolling disc and motor passes in the center pit of demonstration index dial, and the circumference anchor ring of demonstration index dial is carved with scale mark, and the hinge connection of platform and base is provided with inclination angle index dial.Uniform circular motion is carried out by driven by motor rolling disc and counterweight, observe the distance that counterweight is opened, the distance that spring is stretched calculates the size of centrifugal force, the counterweight changing Different Weight or the rotating speed changing motor perception and calculating respectively, the impact of perception and calculating gravity, the inclination angle that can also change platform alleviates the impact of gravity, make test more accurate, this teaching aid has the effect of the understanding uniform circular motion of directly perceived, multi-faceted, multi-angle, contribute to the Thinking Extending of classmates, favourablely to promote the use of.
Description
Technical field
The utility model relates to tutor auxiliary platform teaching aid field, specifically a kind of centrifugal force demonstration teaching aid.
Background technology
In high school physics class, about uniform circular motion part, relate to a lot of knowledge point, if uniform circular motion is variable motion simultaneously, the change in the direction of the speed referred to, the problem of the centripetal acceleration be wherein rather difficult to understand, the acceleration of straight line is understood very well, such as drive in daily life to accelerate, classmates also can personal experience, acceleration in circular motion is not just very directly perceived, and be not fine understanding, the understanding for concepts such as later linear velocity, angular velocity, centripetal force brings certain difficulty.
Utility model content
In order to solve the problem, a kind of centrifugal force demonstration teaching aid is provided to solve the problem.
The technical solution of the utility model is: centrifugal force demonstration teaching aid, comprise base, column chain connection platform on base, platform is provided with the motor placed with plateau levels, and the direct-connected rolling disc of axle head of motor, the outer of rolling disc hangs with spring, spring connects counterweight, axle between rolling disc and motor passes in the center pit of demonstration index dial, and the circumference anchor ring of demonstration index dial is carved with scale mark, and the hinge connection of platform and base is provided with inclination angle index dial.
The utility model has following beneficial effect: carry out uniform circular motion by driven by motor rolling disc and counterweight, observe the distance that counterweight is opened, the effect of perception centrifugal force, the size of centrifugal force can observe the displacement of counterweight when rotating, the distance that calculating spring is stretched calculates the size of centrifugal force, the counterweight simultaneously can changing Different Weight or the rotating speed changing motor perception and calculating respectively, spring is stretched due to perception, the existence (having acceleration just strong and displacement) of known centripetal acceleration, observe the difference of counterweight in the displacement of demonstration index dial above-below direction simultaneously, the impact of perception and calculating gravity, the inclination angle that can also change platform alleviates the impact of gravity, make test more accurate, this teaching aid has intuitively, multi-faceted, the effect of the understanding uniform circular motion of multi-angle, contribute to the Thinking Extending of classmates, favourablely to promote the use of.
Accompanying drawing explanation
Fig. 1 is schematic flow sheet of the present utility model.
