高一物理力学谁来拯救我？ 这是引力的2113问题！到了高二你学了万有引力你就清楚了5261，现在我4102就简单给你解释一下1653。月球表面的重力加速的（g月）是地球表面的1/6，也就是说，在月球表面月球对物体的吸引能力是地球表面的1/6，地球上的重力计算是G=m*10，那月球吸引能力只有1/6就这样算F=m*10*（1/6）运动员举起重物的实质是客服了引力，在地球上举起120Kg也就是克服1200N的重力，那到了月球还是能克服1200N，而月球上要产生1200N的引力就要6倍的质量，也就是6*120=720Kg了。1200N是运动员的固有能力，无论在地球还是月球都一样的，也是此题的标尺。
