从物理角度来说,centreofmass和centreofgravity实际上是相同的,因为gravity是以质量为导向的。在这个问题上,我们提出了centreofgravity的定义:“thepointatwhichtheweightoftheobjectappearstoact》,如果您问一下centreofmass的定义,这是真问题,“thepointwhereallofthemassoftheobjectisconcentrated”。 Whenanobjectissuppo...
Centre of mass算是A-level (alevel)课程中绝对的重点,在物理和数学的mechanics部分中都频繁出现。 严格上的定义是这样的: The center of mass is the unique point at the center of adistribution of mass in space that has the property that theweightedposition vectors relative to this point sum to zero...

The centre-of-mass correction to the nuclear level density formula is derived for two soluble models. The harmonic oscillator model, applicable at low and moderate excitations, shows that this correction may safely be ignored in low-energy nuclear physics. The Fermi-gas model with periodic ...

According to the CMT, the mass acts as if it were concentrated at the centre and the distance will be measured centre to centre for purposes of using Newton's Gmm/d^2 formula. (1) divide the sphere logically into two halves vertically. Each half will have its own centre of mass, ...
The centre of mass of the system of particles is defined as the point where the mass of the whole body is concentrated for the translatory motion. The motion of this point of the centre of mass can be seen as if the mass of the whole body (i.e., the sum of all the particles pre...
