Mass distribution refers to the way in which mass is spread out in an object or system. It is a key concept in physics and engineering, as it affects how objects behave under various forces. For example, the mass distribution of a car influences its stability and handling during turns. In many cases, mass distribution is analyzed using the center of mass, which is the point where the total mass of an object can be considered to be concentrated. Understanding mass distribution is essential in fields like mechanics, aerospace engineering, and architecture to ensure safety and efficiency in design.
