    人教版新課標(biāo)高中物理必修2向心加速度說課稿

    d.某物體沿直線向東運(yùn)動(dòng),原來的速度是5m/s,2s后速度減小到3m/s,求2s內(nèi)物體速度變化。④如何探究物體作勻速圓周運(yùn)動(dòng)時(shí),在Δt時(shí)間內(nèi)的速度變化?分析:有了同一直線上速度變化的鋪墊后,討論物體做勻速圓周運(yùn)動(dòng)速度的變化就比較自然了,為了給向心加速度方向的學(xué)習(xí)打好基礎(chǔ),可以通過小組協(xié)作,進(jìn)一步完成下列思考題,使同學(xué)們認(rèn)識(shí)到:時(shí)間間隔起短,速度變化的方向起接近半徑方向。(多媒體屏幕投影)a.物體沿半徑為1m的軌道做勻速圓周運(yùn)動(dòng),線速度大小為,求1s內(nèi)物體速度變化并畫出1s內(nèi)速度變化的示意圖。b.分別求出上題中物體在0.5s、0.25s內(nèi)速度變化并畫出相應(yīng)的示意圖。由于沒有辦法直接利用實(shí)驗(yàn)來驗(yàn)證速度變化的方向,所以,我們采用提供思考題的方法,引導(dǎo)同學(xué)在合作學(xué)習(xí)、自主探究中完成。有了速度變化的研究為鋪墊,加速度的方向問題就迎刃而解了。
