所谓变加速运动,也叫非匀变速直线(或曲线)运动,是指物体加速度发生变化的运动。纵观近几年的高考物理题,不难发现,变加速运动问题几乎每年都有所涉及。此类题型复杂多变,可能是以选择题的形式定性判断,也可能是以问答题的形式定量计算,属于高考中实现拉开差距的难题,也是学生看到后为之心惊胆战的物理题型之一。因此变加速问题在高三物理复习中占据重要地位,要重视变加速运动问题解题方法的归纳和总结。
The so-called variable speed motion, also known as non-uniform speed linear (or curve) movement, refers to the object acceleration changes in the movement. Throughout the physical examination in recent years college entrance examination, not hard to find, variable speed exercise problems are involved almost every year. Such a complex type of questions and answers may be based on the qualitative choice of questions in the form of judgments may also be in the form of question and answer questions quantitative calculation of the college entrance examination is to open the gap to open the gap is also the students scared to see the physical problems One of the type. Therefore, the variable acceleration problem occupies an important position in the physics reviewing of the third year of high school, and the induction and conclusion of solving the problem of accelerating speed should be emphasized.
