  So here's his figure, and he's got plots of it here.
  他以图示表示 并在这里做了一张图
• 
  
  Ut tensio (as the extension)
  Ut tensio(即伸展量)
• 
  
  sic vis (so the force).
  sic vis (表示力)
• 
  
  So it's linear, the force is how much you stretch it.
  因此 它是线性的 力表示你用多大力量拉伸它
• 
  
  And he has lots of different kinds of springs that do that.
  他用许多不同种类的弹簧做实验
• 
  
  Here's this clock kind of spring, a coil spring,
  这是时钟用弹簧 一种圈状弹簧
• 
  
  just stretching a wire.
  正被拉伸成线圈状
• 
  
  So the force is proportional to the extension.
  因此 力与伸展量成正比
• 
  
  Or another way of saying it is,
  以另一种方式来描述就是
• 
  
  "The potential energy is proportional to the square of the extension."
  势能与变形量的平方成正比
• 
  
  So it's a parabola.
  因此 它是一个拋物线
• 
  
  So that's Hooke's Law, and that's where we'll take up next time.
  这就是虎克定律 下堂课从这里继续
