根据牛顿第二运动定律,物体的加速度与作用力成正比,与质量成反比。公式表达为 F = ma,其中F代表力(单位:牛顿),m为物体的质量(单位:千克),a是加速度(单位:米每二次方秒)。该定律表明,力是质量与加速度的乘积,质量越大或加速度越大,所需的力也越大。若已知其中两个量,可通过公式直接推导第三个量。反馈...

好了,首先说gravitational mass。 牛顿发现具有物质的物件,皆有一个互相吸引对方的特性。如果抄录他在《原理》一书中的说明,就是: Every particle of matter in the universe attracts every other particle with a force which is directly proportional to the product of their masses and inversely...
