Web8 de nov. de 2024 · Figure 4.2.2 – Center of Mass for Two extended objects. For proof of this, let's treat two extended objects (A and B) as collections of lots of point particles (atoms, if you like), and write down their centers of mass (measured from a common origin) in terms of the masses and positions of their atoms. →rcm A = m1A→r1A + m2A→r2A + …. WebTo add to the confusion, a weight is an artefact of calibrated mass normally made from a dense metal. So, unfortunately, weight has three meanings and care should always be taken to appreciate which one is meant in a particular context. Force. Force is a measure of the interaction between bodies. It takes a number of forms including short-range ...
