Description

Physics-studying card

The present invention relates to the amusement Physics-studying card that a kind of middle school student of confession learning and mastering physical knowledge is used.

As everyone knows: the physics subject conceptual abstraction, principle, formula are more, keep from energy Viewpoint set out, mechanics portion, optics portion, electric department etc. all have mutual contact, the knowledge that relates to is wide, flexibility is big, makes middle school student need spend a large amount of time memory of formula and principle.

The purpose of this invention is to provide a kind of help student and understand physics ABC principle, be beneficial to the student again and open up thinking, create learning method preferably, hold the master pulse of each several part and mutual organic connections thereof, knowledge is resided in Physics-studying card among the amusement.

The present invention finishes as follows: it is made up of physical quantity symbol, trigonometric function, constant and image thereof.Wherein phy symbol is 33, is respectively: a, V, T, g, n, ω, φ, h, R, e, S, m, F, Ek, Ep, A, N, Z, ρ, u, p, t, V, Q, ε, l, γ, β, K, λ, E, C, q; 2 of trigonometric functions are respectively: Sina, Cosa; 3 of constants are respectively: 2,1/2 π; 2 of images are respectively: newton and Gauss's head portrait.Above-mentioned each physical quantity symbol, trigonometric function, constant and image; Make four boards respectively, be divided into two kinds of colors, each 2 on every kind of color board amounts to 160 boards.This board can constitute 85 formula.Its method of playing cards is similar with the method for playing Mah-Jong: mainly contain and eat, bump, accord with the board regulation.For example: the someone goes out one " F ", in all the other hold board person's hand " m " and " a " two boards is arranged, and just can " eat " board, constitutes " F=ma "; If in the person's hand of holding the board two " F " are arranged, also can " bump " board, constitute three " F "; If the board in the player hand just in time constitutes one or more physical equations, just can " accord with " board, symbol board person is the victor.In order to reach the purpose of reviewing physical equation, regulation is bumped board and is only permitted twice.In order to reach the effect of the phase of giving, regulation has the clause of keeping the score in board, requires to put question to mutually in amusement, particularly must answer the relevant issues that other people propose to symbol board person, can not answer or insufficient should the deduction of points.
