(同步练习)高中物理人教(新课标)必修1同步练习:2.6伽利略对

高中物理人教(新课标)必修1同步练习:2.6伽利略对自由落体运动的研究B卷(精编)姓名:________ 班级:________ 成绩:________一、单选题 (共9题;共18分)1. (2分)针对伽利略对自由落体运动的研究内容及过程,有以下叙述:①伽利略后来借助数学知识发现,如果速度与位移成正比,将会推导出复杂的结论;②伽利略通过逻辑得出亚里士多德的结论是错误的;③伽利略做了大胆的猜想:落体运动应该是一种简单的运动,落体的速度与时间或位移成正比;④伽利略通过铜球沿阻力很小的斜面滚下这一严谨求实的实验测定,得出只要倾角一定,铜球的加速度不变,他进一步设想当倾角为90°时,运动变为自由落体,其性质不变,且所有物体下落的加速度都一样,到此人类终于认识到自由落体运动是匀变速直线运动了.根据伽利略研究的真实过程,请你做出科学合理的排序,你认为正确的是()A . ①②③④B . ②③①④C . ①③②④D . ②①③④2. (2分) (2018高一上·金东期中) 如油画所示是伽利略研究自由落体运动时的情景,他设计并做了小球在斜面上运动的实验,关于这个实验的下列说法中不符合史实的是()A . 伽利略以实验来检验速度与时间成正比的猜想是否真实B . 伽利略让小球沿阻力很小的斜面滚下是为了“冲淡”重力的影响C . 伽利略通过实验发现小球沿斜面滚下的运动是匀加速直线运动D . 伽利略用实验而不是外推的方法得到斜面倾角增大到90°小球仍然会保持匀加速运动3. (2分)伽利略在研究自由落体运动时,首先大胆地提出了“重物与轻物应该下落得同样快,落体运动也一定是一种最简单的变速运动”的观点,在研究力和运动的关系时,大胆地做出了“当球沿水平面滚动时,它的速度应该不增也不减”的判断…这一认识的飞跃过程在科学探究中称为“科学猜想”,它孕育了科学的重大发现.科学的猜想,能让人们在科学探究中把握住探究的方向,正确地设计实验,明确所需测量的物理量.科学猜想的提出,一般经历的过程是()A . 认真观察现象,凭借感觉,大胆地猜想B . 认真观察现象,经逻辑分析、推理判断,大胆地猜想C . 认真观察现象,凭借生活经验,大胆地猜想D . 认真观察现象,凭实验验证,大胆地猜想4. (2分)关于物理学思想方法,下列说法中正确的是()A . 著名的伽利略斜面实验,主要应用了控制变量方法B . 在定义“速度”、“加速度”等物理量时,主要应用了比值的方法C . 在研究加速度a和外力F、质量m的关系时,主要应用了等效替代的方法D . 在研究气体的温度不变时,压强与体积的关系时,主要应用了理想实验方法5. (2分) (2020高一上·重庆期中) 如图所示是伽利略研究自由落体运动时的情景,他设计并做了小球在斜面上运动的实验。
