1　问题的提出我们知道,在地球表面附近,物体所受地球对它的万有引力约等于该物体的重力.可是现在不少教辅用书、复习资料都想当然地推广为:在任何星球表面附近,物体所受到的万有引力均约等于其重力.笔者认为,这种推广无凭无据,有必要提出来予以澄清.2　数据论证为了说明这一问 1 As we know the problem, we know that near the surface of the earth, the universal gravity of an object by the earth is approximately equal to the gravity of the object. However, many textbooks and review materials are now naturally promoted as objects near the surface of any planet. The universal gravitation received is equal to its gravity. The author believes that such promotion has no basis, and it is necessary to propose it for clarification. 2 Data demonstration To illustrate this question
