1、匀速直线运动精华总结1、速度:物理学中将 位移与发生位移所用的时间的比值定义为速度。用公式表示为:V=2、瞬时速度:在某一时刻或某一位置的速度称为瞬时速度。瞬时速度的大小称为瞬时速率,简称速率。3、加速度:物理学中,用 速度的改变量?V 与发生这一改变所用时间?t 的比值,定量地描述物体速度变化的快慢,并将这个比值定义为加速度。=单位:米每二次方秒;m/S2即为加速度;即为一次函数图象的斜率;加速度的方向与斜率的正负一致。速度与加速度的概念对比:速度:位移与发生位移所用的时间的比值加速度:速度的改变量 与发生这一改变所用时间?t 的比值4、匀变速直线运动:在物理学中,速度随时间均匀变化,即加速
