Coordination is the ability to move two or more body parts under control, smoothly and efficiently. It involves the integration of movements to produce successful actions, such as hand-eye coordination, which is essential for activities like catching a ball or handwriting.

Strength is the ability of muscles to exert force against resistance. As children grow, their muscle strength increases, allowing them to perform tasks like climbing, carrying objects, and participating in sports activities that require physical exertion.

Flexibility refers to the range of motion in a joint or group of joints. It is important for overall movement efficiency and helps reduce the risk of injuries. Stretching exercises can help improve flexibility in children.

Balance is the ability to maintain the body's center of mass over its base of support. It is crucial for activities like walking, running, and standing on one leg. Balance skills develop as children grow and play.

Agility involves the ability to change body position quickly and effectively while maintaining control. It is important for activities that require quick direction changes, such as sports like soccer or basketball. Agility can be improved through specific drills and activities.

Physical growth milestones include changes in height, weight, and body proportions as children progress from infancy through adolescence. These milestones are influenced by various factors like genetics, nutrition, and overall health.

Understanding and monitoring physical development milestones can help parents and caregivers support children's overall well-being and identify any potential delays or concerns that may require intervention.
