Which term refers to physical changes that can be measured?

The term that refers to physical changes that can be measured is "Growth." This concept is primarily associated with quantifiable changes in size, weight, height, and other physical attributes over time in organisms. Growth is a clear indicator of physical maturation and is typically measured in standard units, making it distinctly observable and assessable in a variety of contexts, such as in children, plants, and animals.

In contrast, other terms like development, change, and transition encompass a broader range of meanings. "Development" often refers to qualitative improvements or progress in capabilities, skills, or emotional and social maturity, which are not strictly measurable in the same physical manner. "Change" is a general term that implies any alteration and does not specify the nature of that alteration, whether it be physical, emotional, or structural. Meanwhile, "transition" signifies a process of moving from one state to another, often encompassing changes in phases of life or conditions, but again does not pertain exclusively to measurable physical changes. Therefore, "Growth" is the most accurate term regarding measurable physical changes.
