人教版新課標(biāo)高中物理必修2功率教案2篇
1．用CAI課件模擬汽車的啟動過程。師生共同討論：①如果作用在物體上的力為恒力，且物體以勻速運(yùn)動，則力對物體做功的功率保持不變。此情況下，任意一段時間內(nèi)的平均功率與任一瞬時的瞬時功率都是相同的。②很多動力機(jī)器通常有一個額定功率，且通常使其在額定功率狀態(tài)工作（如汽車），根據(jù)P=FV可知：當(dāng)路面阻力較小時，牽引力也小，速度大，即汽車可以跑得快些；當(dāng)路面阻力較大，或爬坡時，需要比較大的牽引力，速度必須小。這就是爬坡時汽車換低速擋的道理。③如果動力機(jī)器在實(shí)際功率小于額定功率的條件下工作，例如汽車剛剛起動后的一段時間內(nèi)，速度逐漸增大過程中，牽引力仍可增大，即F和v可以同時增大，但是這一情況應(yīng)以二者乘積等于額定功率為限度，即當(dāng)實(shí)際功率大于額定功率以后，這種情況不可能實(shí)現(xiàn)。
