Abstract
The invention provides a teaching aid for an impact experiment. The teaching aid is characterized by comprising a box, an upper cover, wood blocks and small iron balls. The upper cover is connected with the box, corresponding grooves are formed in the upper cover and the box, and the wood blocks are placed on the grooves in the box. The multiple sets of grooves are formed. The multiple wood blocks are arranged and different in mass. The teaching aid is simple in structure and convenient and easy to use, and the experiment that the small balls impact the objects different in mass to generate different effects is convenient to demonstrate visually.
Description
Technical field
The present invention relates to teaching appliance field, be specifically related to a kind of striking experiment teaching aid.
Background technology
Junior physics class, in saying Newton mechanics law, can be talked about striking experiment, and wherein having an experiment is to say that bead is after striking object, owing to being knocked the quality difference of object, result is also different, owing to there is no suitable experiment equipment, generally all glances off.
Summary of the invention
The present invention is the test problem that solves bead shock different quality object different-effect, has proposed a kind of experiment teaching aid.
The technical solution used in the present invention is: a kind of striking experiment teaching aid, it is characterized in that comprising casing, upper cover, wooden unit and little iron ball, and described upper cover is connected with casing, has corresponding groove on upper cover and casing, on the groove of casing, places wooden unit.
Described groove has many groups.
Described wooden unit has multiple, and quality difference.
Beneficial effect of the present invention is: the present invention is simple in structure easy to use, the convenient test of having demonstrated intuitively bead shock different quality object different-effect.
Brief description of the drawings
Fig. 1 structural drawing of the present invention.
Reference numeral: 1-casing, 2-upper cover, 3-groove, 4-wooden unit, 5-bead.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.A kind of striking experiment teaching aid as shown in Figure 1, its feature with comprise casing 1, upper cover 2, wooden unit 4 and bead 5, described upper cover 2 is connected with casing 1, has three groups of corresponding grooves 3 on upper cover 2 and casing 1, places respectively the different wooden units 4 of 3 quality on the groove 3 of casing 1.
When experiment, bead 5 is placed in the groove 3 of upper cover 2, allows little iron ball 4 glide along groove 3, slide into the wooden unit impact effects difference that then groove 3 on casing 1 clashes into 4, three different qualities of wooden unit.
Below be only specific embodiments more of the present invention; above-mentioned concrete structure can not be interpreted as it is limitation of the present invention; in fact, specific embodiments of the invention have a variety of, within every insubstantial modifications of in the present invention conceives, it being made all falls into protection scope of the present invention.
Claims (3)
