Center of Mass: Definition, Equation, How to Find (w/ Examples)

WebQuestion: (1 point) The motion of a solid object can be analyzed by thinking of the mass as concentrated at a single point, the center of mass. If the object has density ρ(x,y,z) at the point (x,y,z) and occupies a region W, then the coordinates (xˉ,yˉ,zˉ) of the centor of mass are given by xˉ=m1∫WxρdVyˉ=m1∫WyρdVzˉ=m1∫WzρdV, where m=∫WρdV is the total … WebUsing this formula, we can calculate the force of gravity between the Earth and Jupiter. Jupiter's mass is approximately 318 times greater than the Earth's mass, so we can simplify the formula as follows: F = G (m1m2/r^2) F = G (318m/r^2) Now, let's assume that the sun has disappeared, and the Earth is at a distance of 778 million kilometers ... WebThe centre of mass of a rigid body does not change as, by definition, it is rigid it cannot be deformed. However, if a body is not rigid, it can be deformed and when it is deformed its centre of mass can possibly but not necessarily change.
