八年级《物理》(人教版)上册第5页的图0.1—5和0.1—6下配有这样的文字——牛顿猜想:拉住月球使它不能逃离的力,跟拉着物体使它落向地面的力,也许是同一种力?上面的猜想促使牛顿发现了万有引力定律.这样才有了今天的通信卫星.
The eighth grade “Physics” (PEP) is on the fifth page of Figures 1 to 5 and 0.1 to 6 with this text - Newton’s conjecture: Pulling the Moon so that it can’t escape the force, and pulling it to make it The force that falls to the ground, perhaps the same kind of force? The above conjecture prompted Newton to discover the law of universal gravitation. This has led to today’s communications satellite.
