Abstract
The utility model relates to the field of test appliances and discloses a multifunctional demonstration instrument for elastic collision. The scheme is that a demonstration table is provided with a plane area and two inclined plane areas, wherein a plurality of electromagnets are arranged on the inclined plane areas and respectively connected with sockets through lead wires; and a battery is connected with two plugs through a lead wire and a switch. The demonstration instrument can be used for demonstrating the relationship of conversion between potential energy and kinetic energy, and the energy conversion relationship after elastic collision of two spheres, and improves the physics teaching quality.
Description
Technical field
The utility model relates to a kind of experimental apparatus, especially is a kind of multi-functional elastic collision demonstrator.
Background technology
In college physics teaching, the potential energy converting and energy that relates to energy conversion such as object is the conversion that kinetic energy, spheroid carry out energy after the elastic collision, because energy is not the class things that naked eyes can intuitively be seen, more abstract, simple quote law, theory is imparted knowledge to students and is difficult to play the good effect of giving lessons.
The utility model content
For overcoming the deficiencies in the prior art, the utility model provides a kind of multi-functional elastic collision demonstrator that demonstrating energy conversion and spheroid carry out the elastic collision test that carries out.
For realizing above-mentioned technical purpose, the utility model is realized by the following technical solutions: a kind of multi-functional elastic collision demonstrator, constitute by Demonstration table, battery, switch, lead, Demonstration table is provided with a plane area, the two ends of plane area upwards are provided with beveled region, axis, two beveled region upper edges is uniformly distributed with some electromagnet, and electromagnet is connected with socket respectively by lead, and battery connects two plugs by lead, switch.
When carrying out the demonstration of potential energy converting and energy kinetic energy, a plug is inserted in the socket, corresponding electromagnet produces attractive force, one steel ball is placed on the electromagnet place, stable back off switch stops battery and powers to electromagnet, steel ball is rolled in the plane area automatically, and the length that can roll according to the height of steel ball when the inclined-plane, at plane domain calculates the transformational relation of potential energy, kinetic energy.
When carrying out the demonstration of spheroid elastic collision, two plugs are inserted respectively on two sockets in the inclined-plane, corresponding two electromagnet produce gravitation, respectively two steel balls are placed on the electromagnet place, treat the stable back of steel ball off switch, two steel balls tumble to plane area under action of gravity, and bump, can be according to position, the two spheroids initial height of spheroid at plane area, study the energy conversion relation after the spheroid elastic collision.
The utlity model has following beneficial effect: can demonstrate the transfer process of spheroid potential energy, kinetic energy intuitively, and can study the transfer process that spheroid carries out energy after the elastic collision, improve the teaching efficiency in the physics course.
