If you left your book on the table overnight, you would find the following morning that it was still exactly when you had left it, provided nobody had moved it. If a ball is made to roll on a very smooth surface, it will roll a long distance unless something stops it or changes its direction. This tendency of an object to remain at rest unless something moves it and to continue moving unless something stops it is known as the Law of Inertia.
The following examples show the truth of this law.
(a)Put a table-cloth on a table and arrange a pile of books on it. Hold one edge of the tablecloth and pull it quickly. The table-cloth will come off, leaving the pile of books undisturbed.
(b)Place a small piece of cardboard on an open jar and place a coin on it directly over its mouth. Use one finger to flick the piece of cardboard away. You will" notice that the coin drops into the jar.
(c)Sitting in a car which starts suddenly, you feel you are jerked backwards. In fact, you are not jerked backwards. Your lower half, which is in contact with the cushion, is forced to move forward with the car, and the upper part of your body, which remained at rest, is left behind. [br] Which of the following is an example of inertia?
选项
A、A boat can stay on water.
B、A plane can fly in the air.
C、You can walk faster on a very smooth surface.
D、You can go forward and backward on a swing.
答案
D
解析
本题考查推理判断。根据第一段最后一句“This tendency of an object to remain atrest unless something moves it and to continue moving unless something stops it is known as theLaw of Inertia.”惯性的定义可知,四个选项中,只有D项荡秋千人的来回摆动属于惯性现象。所以,答案是D。
