一个有价值的物理学理想实验
胡良
一个物体的最大速度是多少？
第一种情况，如果所有物体的最大速度都是相同的，则这个最大速度一定是常数，而该最大速度的具体数值是多少。
第二种情况，如果不同物体的最大速度是不相同的；则伽利略在比萨斜塔上做的实验是否正确，就值得进一步论证。
第三种情况，假设有一个铁球及一个木球，从无穷远处落向地球；则最终落向地球的速度是否完全相同。
What is the maximum speed of an object?
In the first case, if the maximum speed of all objects is the same, then the maximum speed must be a constant, and what is the specific value of the maximum speed.
In the second case, if the maximum speeds of different objects are not the same; whether Galileo's experiment on the Leaning Tower of Pisa is correct, it is worthy of further demonstration.
In the third case, suppose there is an iron ball and a wooden ball falling to the earth from infinity; whether the speed of the final falling to the earth is exactly the same.
