物理峰峦高又大,口诀熟记咱不怕,知识规律帮你理,学好物理不算啥。运用基本公式法,“知三求二”好算法,中间时刻速度法,初速度为零比例法,再加几何图象法,求解运动好方法。自由落体常回忆,初速度为零a为g,竖直上抛找初速,上升高度心有数,上升下落为对称,整个过程匀减速。受力分析先重力,然后接触力和场力,
Rising peaks and large physical, formulas memorize we are not afraid, the laws of knowledge to help you manage, learning physics is not what. Use the basic formula method, “know three seeking two ” a good algorithm, the intermediate time velocity method, the initial velocity of zero ratio method, coupled with geometric image method, to solve the good exercise method. Frequent free-fall memories, the initial speed of zero a for the g, the vertical speed to find the initial velocity, the height of a few ascent, ascent and descent for symmetry, the whole process of uniform deceleration. Force analysis of gravity, and then contact force and field strength,
