Embodiment 1

[0040] For ease of understanding, see Figure 1 to Figure 5 , an embodiment of a centripetal force experimental device provided by the present application, including a base 1, a turntable 7, a controller, a rotating motor 3, a photoelectric gate, a tension sensor 9, a pressure sensor, several spheres 14 with different masses but the same size, A number of flexible ropes 11 with different lengths and no elasticity.

[0041] The turntable 7 is located above the base 1, and the rotary motor 3 is arranged below the base 1. The center of the turntable 7 is provided with a central shaft 8 that runs through the turntable 7 vertically. The central shaft 8 passes through the top of the base 1 and is connected to the rotating shaft of the rotary motor 3. 3 is used for driving turntable 7 to rotate.

[0042] The upper surface of the rotating disk 7 is provided with a limiting groove 12 connected to the center of the rotating disk 7. The limiting groove 12 is used to limit the ball 14 to r...

Embodiment 2

[0054] For ease of understanding, see Figure 1 to Figure 5 , this embodiment is a further improvement of the centripetal force experimental device provided in embodiment 1, the depth of the limiting groove 12 is greater than the radius of the sphere 14 .

[0055] The limit groove 12 is connected from the edge of the turntable 7 to the center, and the end of the limit groove 12 away from the center of the turntable 7 is provided with a baffle plate 15 for preventing the ball 14 from flying out.

[0056] The side of the baffle plate 15 close to the center of the turntable 7 is provided with a rubber layer.

[0057] The upper end of the baffle plate 15 is inclined towards the center of the rotating disk 7 .

[0058] It should be noted that the center of gravity of the sphere 14 is located at the center of the sphere, and the depth of the limiting groove 12 is set to be greater than the radius of the sphere 14 so that the sphere 14 is not easy to roll out of the limiting groove ...

Embodiment 3

[0060] For ease of understanding, see Figure 1 to Figure 5 , this embodiment is a further improvement of the centripetal force experimental device provided in embodiment 1, and a transparent protective cover for covering the turntable 7 is provided above the base 1 .

[0061] The ball 14 is provided with a through hole 16 , and the flexible rope 11 passes through the through hole 16 to connect with the ball 14 .

[0062] Buckles 17 are provided at both ends of the flexible rope 11 , and the flexible rope 11 is respectively connected to the pull ring 10 and the through hole 16 through the buckles 17 .

[0063] The base 1 is provided with height-adjustable support feet 2 .

[0064] There is a rubber layer at the bottom of the support foot 2

[0065] It should be noted that the protective cover plays the role of protecting the turntable 7, and can also prevent the ball 14 from flying out during the test. The flexible rope 11 is connected to the sphere 14 through the through h...

Abstract

The invention discloses a centripetal force experimental device. The centripetal force experimental device comprises a base, a rotating disc, a controller, a rotating motor, a photoelectric door, a tension sensor, a pressure sensor, a sphere and a flexible rope without elasticity, wherein a central shaft is arranged at the center of the rotating disc; the rotating motor is used for driving the rotating disc to rotate; a limit slot is arranged on the rotating disc; the center shaft is sleeved with the tension sensor; a pull ring of the tension sensor faces the limit slot; a limiting ring is arranged in the limit slot; the flexible rope penetrates through the limiting ring and is connected with the pull ring and the sphere; the center of the pull ring, the center of the limiting ring and the center of the sphere are located on the same horizontal line, and the horizontal line penetrates through the center of the center shaft; the pressure sensor is annularly arranged on the inner wall of the limiting ring; a straight rod is arranged at the bottom of the rotating disc; and the photoelectric door is used for monitoring rotation of the straight rod. The invention relates to the technical field of physics experimental equipment, and aims to solve the technical problems that an existing centripetal force demonstration experiment is not visual, has large errors, and cannot obtain experiment data.

Description

technical field [0001] The invention relates to the technical field of physics experiment equipment, in particular to a centripetal force experiment device. Background technique [0002] Science and technology projects refer to projects that are independently projected with scientific research and technological development as their content, and their purpose is to solve scientific and technological problems arising in economic and social development. To carry out scientific research and technology development requires many scientific experiments, and to carry out scientific experiments requires the use of various experimental devices. [0003] Centripetal force is the resultant external force directed to the center of the circle (center of curvature) when an object moves along a circular or curved track. The formula for centripetal force is F=mω 2 r (F is the centripetal force, m is the mass of the object, ω is the angular velocity, and r is the radius of motion of the obje...
