    一般情況下,凡是支持物對物體的支持力,都是支持物因發(fā)生形變而對物體產(chǎn)生彈力。所以支持力的方向總是垂直于支持面而指向被支持的物體。例1:放在水平桌面上的書書由于重力的作用而壓迫桌面,使書和桌面同時發(fā)生微小形變,要恢復(fù)原狀,對桌面產(chǎn)生垂直于桌面向下的彈力f1,這就是書對桌面的壓力;桌面由于發(fā)生微小的形變,對書產(chǎn)生垂直于書面向上的彈力f2,這就是桌面對書的支持力。學(xué)生分析:靜止地放在傾斜木板上的書,書對木板的壓力和木板對書的支持力。并畫出力的示意圖。結(jié)論:壓力、支持力都是彈力。壓力的方向總是垂直于支持面而指向被壓的物體,支持力的方向總是垂直于支持面而指向被支持的物體。引導(dǎo)學(xué)生分析靜止時,懸繩對重物的拉力及方向。引導(dǎo)得出:懸掛物由于重力的作用而拉緊懸繩,使重物、懸繩同時發(fā)生微小的形變。重物由于發(fā)生微小的形變,對懸繩產(chǎn)生豎直向下的彈力f1,這是物對繩的拉力;懸繩由于發(fā)生微小形變,對物產(chǎn)生豎直向上的彈力f2,這就是繩對物體的拉力。

    人教版高中生物必修2基因在染色體上說課稿

    三、孟德爾遺傳規(guī)律的現(xiàn)代解釋①分離定律:在雜合體的細胞中,位于一對同源染色體上的等位基因,具有一定的獨立性;在減數(shù)分裂形成配子的過程中,等位基因隨同源染色體的分開而分離,獨立地隨配子遺傳給后代。②自由組合定律:位于非同源染色體上的非等位基因的分離或組合是互不干擾的;在減數(shù)分裂過程中,同源染色體的等位基因彼此分離的同時,非同源染色體上的非等位基因自由組合。總結(jié):再次強調(diào)孟德爾遺傳定律的現(xiàn)代解釋課堂練習(xí):書本31頁6、教學(xué)反思:本節(jié)課設(shè)置了一系列問題情境,層層設(shè)問,在學(xué)生答問、質(zhì)疑、討論過程中讓學(xué)生建構(gòu)新概念和新的知識體系,并通過教師及時掌握反饋信息,適時點撥、調(diào)節(jié),讓學(xué)生在推理判斷中培養(yǎng)良好的思維習(xí)慣和對知識的遷移能力,而且通過留出一定的時間讓學(xué)生提問,體現(xiàn)了以學(xué)生為主體的思想。
