2020-2021 中考物理(浮力类问题提高练习题)压轴题训练附答案

2020-2021 中考物理(浮力类问题提高练习题)压轴题训练附答案

一、初中物理浮力类问题

1.如图所示,台秤的托盘上放一个装有水的平底烧杯,一个不吸水的木块用细线系在烧杯底浸没在水中,剪掉木块以后,木块上浮至静止,下列说法正确的是( )

A.剪断细线前,木块所受的浮力等于木块的重力

B.剪断细线前,托盘受到的压力等于烧杯与水的重力之和

C.整个过程,水对杯底的压力变化量等于木块浮力的变化量

D.整个过程,托盘受到压力的变化量等于木块浮力的变化量

【答案】C

【解析】

【分析】

【详解】

A.木块被用细线吊着浸没在水中,木块受到竖直向下的重力和拉力,以及竖直向上的浮力,浮力等于木块的重力加上绳子对它的拉力,故A错误;

B.根据力的平衡的条件可知,托盘受到的压力等于水杯的重力+水的重力+木块的重力,故B错误;

C.木块浸入水中,此时木块受到的浮力是大于重力的,当绳子剪断后,木块上浮,最终漂浮在水面上,此时浮力等于重力,同时烧杯内水位会下降,下降的这部分水的重力等于木块漂浮在水面上时减少的排开水的重力,即减小的浮力,因为力的作用是相互的,所以水对杯底的压力变化量等于木块浮力的变化量,故C正确;

D.把烧杯、水和木块作为一个整体,整个过程中托盘受到的压力始终等于烧杯、水和木块的重力之和,托盘受到压力的不变;而木块剪断细线之后,排开水的体积变小,浮力变小,所以浮力变小,因此整个过程,托盘受到压力的变化量不等于木块浮力的变化量,故D错误。

故选C。

2.如图所示,柱形容器的底面积为500cm2,重为5N的木块A在水中处于静止状态,此时绳子的拉力为3N。若绳子突然断了,待木块再次静止时,容器中水面将下降的高度是( )

A.4.0×103m B.6.0×10-3m C.1.0×10-2m D.1.6×10-2m

【答案】B

【解析】

【分析】

【详解】

木块A静止时,受到重力G,浮力F浮以及绳子的拉力F拉,因为拉力方向为竖直向下,所以三者之间的关系为

FGF浮拉
