The analogy would be sensible if the center of mass were the location where the gravitational force - acting on masses - acts. The gravitational force is given by G m 1 m 2 / r 2, and similarly, the electrostatic one could be Q 1 Q 2 / 4 π ϵ r 2. princeton municipal rv park and campground

Integral definition of center of mass

NettetThe centre of mass of an object is the point at which the weight of the object may be considered to act The position of the centre of mass of uniform regular solid is at its centre For example, for a person standing upright, their centre of mass is roughly in the middle of the body behind the navel, and for a sphere, it is at the centre NettetMy instructor has taught us to calculate center of mass using the following formula: x ¯ = ∫ a b x ρ ( x) d x ∫ a b ρ ( x) d x. Where x = x ¯ is the center of mass, and ρ ( x) is the density function. From what I understand, this formula essentially calculates the mean of the distribution of mass along the rod.
