10. (4.0分) A typical example from mechanics is the notion that an object will come to rest unless it is kept in motion by a force. This is contrary to Newton's first law and the scientific view of motion — but it works in daily life! Which of the following statement is correct?A. The notion that an object will come to rest unless it is kept in motion by a force is a typical example of Newton's first law.B. In daily life people hold the conception that an object will not come to rest unless a force acts on it.C. An object will not come to rest unless a force acts on it, but in daily life people tend to hold the contrary conception.D. The notion is true that an object will come to rest unless it is kept in motion by a force.

解析
本题考查对文章内容的理解以及对各选项的分析判断。解题的关键在于准确理解题干中所描述的力学观念以及牛顿第一定律和日常观念之间的关系,然后逐一分析每个选项是否符合原文意思。
- 分析选项A:
- 题干明确提到“A typical example from mechanics is the notion that an object will come to rest unless it is kept in motion by a force. This is contrary to Newton's first law”,即物体除非受到力的作用否则会静止这一观念与牛顿第一定律相悖。
- 而选项A说该观念是牛顿第一定律的典型例子,这与原文不符,所以选项A错误。
- 分析选项B:
- 题干表明“an object will come to rest unless it is kept in motion by a force. This... works in daily life”,意思是在日常生活中人们认为物体除非受到力的作用否则会静止。
- 而选项B说在日常生活中人们认为除非有力作用物体才不会静止,与原文意思相反,所以选项B错误。
- 分析选项C:
- 根据牛顿第一定律,物体在不受外力作用时会保持静止或匀速直线运动状态,也就是物体不会静止除非有力作用在它上面。
- 同时题干又指出“an object will come to rest unless it is kept in motion by a force. This... works in daily life”,说明日常生活中人们持相反的观念。
- 所以选项C的表述与原文和科学知识都相符,选项C正确。
- 分析选项D:
- 题干已经说明该观念与牛顿第一定律相悖,而牛顿第一定律是科学的运动观。
- 所以该观念并不是正确的,选项D错误。
