Physical development refers to the growth process people experience, and it impacts other types of development. Explore the definition and examples of physical development and learn about childhood, adolescence, and aging.

Childhood and adolescence are times of great physical changes. Children grow taller and become better at controlling their bodies. Adolescents develop body hair and other adult features as they make their way into full adulthood. These changes seem pretty straightforward. If Johnny is two inches taller or his hat size goes up, it means that he’s physically growing.
