长期以来,物理被认为是一门难学的科目,甚至谈及色变,概叹不已。物理真的如此难学?事实上,众多在物理学科上取得优异成绩并作出重大贡献的人们已经用实际行动告诉了我们:物理是可以学好的,它并没有那么可怕,当你走近它,了解它之后,你会发现它其实很有趣,而且很有用。譬如:成熟的苹果总是会自然地落向地面而不会飞向太空——万有引力;鞋底、车轮的表面做得越粗糙越不容易打滑——摩擦力;我们借助手机利用电磁波传递声音进行远距离通话——声音的传播。 For a long time, physics was considered a difficult subject, and even talked about color change. Physics is really so difficult to learn? In fact, many people who have made outstanding achievements in physics and made significant contributions have told us in practical terms: Physics is good to learn, it is not so terrible, and as you approach it, After you understand it, you will find that it is actually very interesting, and very useful. For example: mature apples will always fall naturally to the ground without flying into space - gravitation; soles, the rougher the wheels do the more difficult to slippery - friction; we use mobile phones to use electromagnetic waves to carry sound far Distance calls - the spread of sound.
