說明
機械物理簡介
透過學習關於簡單機械原理以及知道如何使用它們,使複雜的任務更容易,從而開始您對機械物理學的研究。操場上的翹翹板、後院的獨輪車、學校前的旗桿─這些所有都是現實世界中簡單機械的例子!開始組裝、調查和實驗吧!發現物理學是如何存在我們身邊。
透過26個模型的組裝練習,你可以研究全部共6個經典的簡單機械原理─車輪與車軸、槓桿、斜面、螺絲和楔子─以及齒輪。從簡單的模型開始,深入了解正在發揮作用的基本原理,然後轉向更大、更複雜的模型,看它們如何一起運作。產品包含一個特殊設計的彈簧秤,以便你可以測量機器如何改變力的方向和大小,使運作更容易。
Description
INTRODUCTION TO MECHANICAL PHYSICS
Jumpstart your study of mechanical physics by learning all about simple machines and how they’re used to make complex tasks easier to do. The seesaw at the playground, the wheelbarrow in your backyard, the flagpole in front of your school - all of these are examples of simple machines in the real world! So start building, investigating, and experimenting to discover how physics is all around us.
Through 26 model-building exercises, you'll investigate all six classic simple machines - wheels and axles, levers, pulleys, inclined planes, screws, and wedges - as well as gears. Start off with simple models to gain a firm understanding of the basic principles at play, and then move onto larger, more complex models to push the machines harder and see how they can work together. Also included is a specially designed spring scale so that you can measure how the machines change the direction and magnitude of forces, making work easier to do.
