You can't accomplish your goal of mastering the language unless you work at it for years. Well, it sounds as if I'm exag-gerating the difficulties, but the fact is I'm only telling the truth. 2) The principal is somewhat disappointed with the performance of the children. From what she has gathered, some of the teaching staff have neglected their pupils. She has just announced that strict work regulations have been made and that they apply to both Chinese and overseas teachers. 3) The teacher-directed and the child-directed approaches to teaching art represent two ex-tremes of opinion. Too many teacher-directed activities cannot be expected to effectively assist children in learning because of the rigid structure. On the other hand, too many child-directed activities may see a curriculum that is totally unstructured and out of con-trol. There are valid reasons to believe a teacher-guided approach would be a superior way to guide children's development. This approach combines some form of structure with the child leading the direction. II. Confusable Words 1. 1) continual 3) continual

大学物理学(第三版)课后习题参考答案

习题1 1.1选择题 (1) 一运动质点在某瞬时位于矢径),(y x r 的端点处，其速度大小为 (A)dt dr (B)dt r d (C)dt r d | | (D) 22)()(dt dy dt dx [答案：D] (2) 一质点作直线运动，某时刻的瞬时速度s m v /2 ，瞬时加速度2 /2s m a ，则一秒钟后质点的速度 (A)等于零 (B)等于-2m/s (C)等于2m/s (D)不能确定。 [答案：D] (3) 一质点沿半径为R 的圆周作匀速率运动，每t 秒转一圈，在2t 时间间隔中，其平均速度大小和平均速率大小分别为 (A) t R t R 2, 2 (B) t R 2,0 (C) 0,0 (D) 0,2t R [答案：B] 1.2填空题 (1) 一质点，以1 s m 的匀速率作半径为5m 的圆周运动，则该质点在5s 内，位移的大小是；经过的路程是。 [答案： 10m ； 5πm] (2) 一质点沿x 方向运动，其加速度随时间的变化关系为a=3+2t (SI)，如果初始时刻质点的速度v 0为5m·s -1，则当t 为3s 时，质点的速度v= 。 [答案： 23m·s -1 ] (3) 轮船在水上以相对于水的速度1V 航行，水流速度为2V ，一人相对于甲板以速度3V 行走。如人相对于岸静止，则1V 、2V 和3V 的关系是。 [答案： 0321 V V V ]

1.3 一个物体能否被看作质点，你认为主要由以下三个因素中哪个因素决定： (1) 物体的大小和形状； (2) 物体的内部结构； (3) 所研究问题的性质。解：只有当物体的尺寸远小于其运动范围时才可忽略其大小的影响，因此主要由所研究问题的性质决定。 1.4 下面几个质点运动学方程，哪个是匀变速直线运动？（1）x=4t-3；（2）x=-4t 3+3t 2+6；（3）x=-2t 2+8t+4；（4）x=2/t 2-4/t 。给出这个匀变速直线运动在t=3s 时的速度和加速度，并说明该时刻运动是加速的还是减速的。（x 单位为m ，t 单位为s ）解：匀变速直线运动即加速度为不等于零的常数时的运动。加速度又是位移对时间的两阶导数。于是可得（3）为匀变速直线运动。其速度和加速度表达式分别为 2 2484 dx v t dt d x a dt t=3s 时的速度和加速度分别为v =20m/s ，a =4m/s 2。因加速度为正所以是加速的。 1.5 在以下几种运动中，质点的切向加速度、法向加速度以及加速度哪些为零哪些不为零？ (1) 匀速直线运动；(2) 匀速曲线运动；(3) 变速直线运动；(4) 变速曲线运动。解：(1) 质点作匀速直线运动时，其切向加速度、法向加速度及加速度均为零； (2) 质点作匀速曲线运动时，其切向加速度为零，法向加速度和加速度均不为零； (3) 质点作变速直线运动时，其法向加速度为零，切向加速度和加速度均不为零； (4) 质点作变速曲线运动时，其切向加速度、法向加速度及加速度均不为零。 1.6 ｜r ｜与r 有无不同?t d d r 和d d r t 有无不同? t d d v 和t d d v 有无不同?其不同在哪里?试举例说明．解：（1）r 是位移的模， r 是位矢的模的增量，即r 12r r ，12r r r ；（2） t d d r 是速度的模，即t d d r v t s d d . t r d d 只是速度在径向上的分量. ∵有r r ?r （式中r ?叫做单位矢），则 t ?r ?t r t d d d d d d r r r 式中 t r d d 就是速度在径向上的分量，
