如果我把一池水放在秤上,讓某人進入游泳池,但沒有觸及底部或任何側面,他們會增加游泳池的重量嗎？

首先，我們必須了解浮力的概念。浮力是作用在浸沒在流體（例如水）中的物體上的向上力。根據阿基米德原理，作用在浸沒物體上的浮力等於物體排開流體的重量。

在這個案例中，當某人進入游泳池時，他們的體積會排開相當於他們體重的水。因此，雖然他們沒有觸及 Schwimmbecken 的底部或側面，但他們仍然會增加 Schwimmbecken 的淨重量，因為他們排開的水的重量會被秤子測量到。

換句話說，秤子測量的是游泳池和水以及游泳者總重量，因此游泳者的重量會增加游泳池的總重量。

相關問題及簡要回答：

  1. 浮力是什麼？：作用在浸沒在流體中的物體上的向上力。
  2. 阿基米德原理是什麼？：作用在浸沒物體上的浮力等於物體排開流體的重量。
  3. 游泳者進入游泳池會不會增加游泳池的重量？：會，因為他們排開的水的重量會被秤子測量到。
  4. 游泳者沒有觸及游泳池底部或側面，會影響秤子測量嗎？：不會，因為浮力與接觸面積無關。
  5. 浮力與物體的密度有關嗎？：是的，物體的密度越大，排開的流體越多，浮力越大。
