這部分內回容主要考察的是位移答的知識點:
位移用位移表示物體(質點)的位置變化。定義為:由初位置到末位置的有向線段。其大小與路徑無關,方向由起點指向終點。它是一個有大小和方向的物理量,即矢量。
位移(displacement) 質點的位置變動,用連接先後兩位置的有向線段表示,如圖所示,在瞬時t質點位於Q點,瞬時t+△t位於Q′點,則矢量表示質點從t時刻開始在△t時間間隔內的位移。它等於Q′點的矢徑與Q點的矢徑之差,即△r=r(t+△t)-r(t)。
與此同時,質點在△t時間間隔內由Q點沿軌跡曲線運動到Q′,所經過的路程是弧長(標量)。因此,位移和路程是兩個不同的概念。當△t很小,位移矢量的模和路程的差為高階小量;當△t→0,兩者相等。
物體在某一段時間內,如果由初位置移到末位置,則由初位置到末位置的有向線段叫做位移。它的大小是運動物體初位置到末位置的直線距離;方向是從初位置指向末位置。位移只與物體運動的始末位置有關,而與運動的軌跡無關。如果質點在運動過程中經過一段時間後回到原處,那麼,路程不為零而位移則為零。
