It can coincide the locating piece into guide groove equipped at least two, locating piece is equipped with the positioning column being adapted to location hole, with locating piece
It is equipped with ball far from disc centre side, locating piece is equipped with can be with the actuation block of ball magnet attraction.
Further, distribution that one is long and the other is short at the guide groove interval and outer end reaches disk edge.
Further, the ball is permanent magnet.
Further, the actuation block is permanent magnet.
Further, the ball falls in guide groove and is attracted with actuation block central contact.
Further, the turntable is equipped with the annular trace concentric with turntable, and each location hole is respectively fallen in wherein together
On track.
Further, the center of turntable is equipped with sphere.
Further, the turntable outer rim is connected with the volume edge for the recycling that upsweeps.
Further, the ball is different colours.
Further, the ball is of different sizes, or is attracted block suction difference.
The present invention is using when by more than two balls respectively by being distributed in determining of being located by connecting in different guide grooves with location hole
Actuation block on the block of position is attracted, and is then started motor and is gradually increased speed, respectively overcomes each ball under the influence of centrifugal force
It is attracted block suction, is displaced outwardly, and then intuitively obtain centripetal force, centrifugal force and factor associated therewith and rule, keeps away along guide groove
Exempt from uninteresting abstract-learning.
Detailed description of the invention
Fig. 1 is overall schematic of the embodiment of the present invention.
Fig. 2 is decomposition diagram of the embodiment of the present invention.
Appended drawing reference: 1 turntable；2 variable-frequency motors；3 controllers；4 keys；5 guide grooves；6 location holes；7 locating pieces；8 positioning columns；

Specific embodiment
The embodiment of the present invention is as shown in Figure 1, 2, the centripetal force centrifugal force physics demonstration device, is used for centripetal force, centrifugal force
With the teaching demonstration of factor associated therewith and rule, including turntable 1 and driving portion, driving portion is equipped with the frequency conversion being connected on pedestal
Motor 2, variable-frequency motor are equipped with controller 3, and controller is connected with speed control key 4, and controller is also connected with display screen and is used for
Show that speed or speed class, disk axes and variable-frequency motor drive axis connection, turntable is equipped with to be stretched from center to fringe radiation
Open up circumferentially distributed guide groove 5, the present embodiment guide groove is six long six short, distribution that one is long and the other is short at interval and outer end reaches disk edge,
It is equipped with along the radially-arranged location hole 6 of turntable in guide groove, being additionally provided at least two can coincide locating piece 7 into guide groove, positioning
Block is equipped with the positioning column 8 being adapted to location hole, is equipped with ball 9 far from disc centre side with locating piece, locating piece is equipped with energy
At least one is permanent magnet for enough and ball magnet attraction actuation block 10, ball and actuation block, and the two can inhale together, with the suction generation
Table centripetal force, the present embodiment using when ball fall in guide groove be attracted block central contact be attracted, turntable be equipped with turntable it is concentric
Annular trace, linear velocity is identical on same track, and the present embodiment shows as circular bar 12, and each location hole respectively falls in wherein one
On road track, turntable outer rim is connected with the volume for the recycling that upsweeps along 11.
The present invention using when by least two locating pieces be placed in different guide grooves by location hole position, be attracted ball respectively
On the actuation block on each locating piece, it is of different sizes and correspond to that be attracted block suction identical that different balls can be used weight, different
Ball can also be used weight it is identical and correspond to be attracted block suction it is different, starting motor simultaneously speed is gradually increased by safety check,
It respectively overcomes each ball under the influence of centrifugal force and is attracted block suction, be displaced outwardly along guide groove, record each ball and be detached from when being attracted
Speed or speed class value can intuitively obtain centripetal force, centrifugal force and factor associated therewith and rule, to overcome it is larger to
Mental and physical efforts need larger speed to obtain larger centrifugal force.
