Center of gravity and the center of mass

Click For Summary
SUMMARY

The center of mass and the center of gravity are distinct concepts in physics. The center of mass is defined as the point where all mass of a body can be considered concentrated, while the center of gravity is where all weight is concentrated. In practical applications, both points can often be treated as equivalent, particularly when analyzing static bodies. The center of gravity is typically understood as a horizontal location, with the center of mass being a more general three-dimensional concept.

PREREQUISITES

:cry: been wonderin' for an hour already nac somebody please answer if there is a difference between the center of gravity and the center of mass if there is, what is it?

The center of mass is a point on a body where you can consider all the mass to be concentrated, whereas the center of gravity is a point on a body where you can consider all the WEIGHT to be concentrated.
 
In any realistic situation, you can treat them both as the center-of-mass.

I've seen center-of-gravity treated as a horizontal location (as on a floor)
which the center-of-mass is directly above or directly below.
In that interpretation & treatment, center-of-mass, being 3d, is more general.
