图书描述

本书是基础力学的简介，其中重点介绍自由体图的概念。此概念是学习力学的第一个最重要的抽像概念。本书的特点是引导读者经过简单的例题计算来呈现此概念，而不是直接描述。有了这概念的基础理解后，我们将细致化自由体图的概念，更整理为一套可操作的法则，以按此法则用作更复杂的力学解题。本书可作为双语学习的参考教材。

Law of Force, Origin of Force

What is Force

The Intuitive Meaning of Force

You feel a force when someone pushes you.

A force is a push or pull upon an object by another object when the two objects interact with each other.

The Effect of a Force

A force is a push or pull. So we consider the effect of such push and pull to narrow down the actual meaning of ‘Force’.

Let us consider the motion of an object exerted by a force, for example, dragging a luggage. Let us use our intuition to judge: which of the following intuition is correct.

Intuition 1:

A pulling force is needed to keep the motion of the luggage.

That is, a force is needed to keep an object in motion.

Intuition 2:

A pulling force is needed to start the motion of the luggage.

That is, a force is needed to speed up the motion of an object.
