益阳市 2022 年下学期期末质量检测

高一　物理参考答案

一、选择题（1~6 小题为单选题，每小题 4分，共 24 分。7~10 小题为多选题，全部选对的得

5分，选对但不全的得 3分，有选错的得 0分。）

题号 1 2 3 4 5 6 7 8 9 10

答案 C D A B D C AD CD BC AC

三、实验题：本题共 2小题，每空 2分，共 14 分。

11．AC①如图 ②6

【解析】

12．（1）交流电源（2）不需要（3）远小于（4）0.82

【解析】

（1）电磁打点计时器与电火花打点计时器均用交流电源

（2）补偿阻力以后改变质量不影响补偿结果，不需要再补偿

（3）只有满足槽码的质量远小于小车的质量，才能将槽码的总重力视为小车的拉力

（4）由 Δs=aT2得

a=Δs

T2=0 . 82×10−2

0 . 12=0 . 82m/s2

四、计算题：本题共 3小题，第 13 题10 分，第 14 题14 分，第 15 题18 分，共 42 分。

13．（1）雨滴滴落是自由落体运动

h=1

2gt2

··························································2 分

解得下落时间 t=1s················································1 分

落地时的速度

v=gt

······························································2 分

=10m/s·····························································1 分

方向竖直向下······················································1 分

（2）第一滴刚要落地，第六滴恰要下落

所以总共有 5个时间间隔 ·······························2 分

雨滴落地时间：t=1s

所以

Δt=t

n=0. 2 s

········································1 分

14．（1）受力分析如图：

FOAsin30°=FOB················································3 分

FOAcos30°=G··················································3 分

解得

FOB=50

√

················································1 分

（2）由上可知，FOA˃FOB，所以 AO 先断··············2 分

当

FOA=100 N

时AO 绳要断

此时物体的重力 Gmax=FOAcos30°·························3 分

=50

15.（1）对物块 f1=μ1mg··············································1 分

f1=ma 物·····························································1 分

解得物块的加速度 a物=2m/s2···································1 分

对长木板 F合= f1+ f2=μ1mg+μ2×2mg····························1 分

F 合= ma 板···························································1 分

解得长木板的加速度 a板=4m/s2································1 分

（2）使物块不滑离木板，即木板长度至少等于达到共速时两物体的相对位移。

设经时间 t达到共速

FOA

FOB
