势能,是能量一种储存形式,就如同能量储存在食物中,平时对外不放出能量,当到了一个状态,如底下支撑物消失,或是使弹簧变形的你的手离开,这时势能转化为动能,对外放能,就如同能量储存在木头中,平时不放能,见了火,就转化为热能。总的来说,就是能量的一种储存形式。动能和机械能本质上差别不太大,我个人理解动能是一种粗俗的说法,是研究力学时,对运动的物体具有能量大小的解释。而机械能,更多的是表示于转化为其他能,用于表示动能转化为其他能的更专业的解释,而且你可以准确的表示一个具有动能的物体究竟有多少能。势能,表示为物体形状变拉,分子之间因力产生距离大小变化(比如两块磁铁,你强行接近或是搬开,你的能以分子距离形式保存)这就是势能
那个问题,你想想,你自己做功,加大与地球距离,不正如把磁铁拉开,这就有能储存。所以是势能转化为动能。
