What determines the center of mass of an object?

• A. The size of the object
• B. The shape of the object
• C. The mass distribution of the object
• D. The material of the object

Answer: (C)

The center of mass of an object is determined by the mass distribution of the object. This means that how the mass is spread out or concentrated within the object directly influences where the center of mass is located. For instance, if a uniform object has its mass evenly distributed, the center of mass will be at its geometric center. However, if the mass is not evenly distributed—for example, if one part of the object is much heavier than other parts—the center of mass will shift closer to the heavier area. The size of the object, while it can influence the overall distribution, does not itself determine the center of mass without considering how the mass is distributed within that size. Similarly, the shape of the object can affect where the mass is located but is not the primary factor in determining the center of mass. The material of the object could influence the overall weight and physical properties but does not dictate the position of the center of mass unless it directly relates to the mass distribution. Therefore, mass distribution is key to pinpointing the center of mass.
