Which term best describes the ability to control the placement of the body's center of gravity in relation to its support base?

• A. Balance
• B. Coordination
• C. Accuracy
• D. Flexibility

Answer: (A)

Balance is the ability to control the placement of the body's center of gravity in relation to its support base. The center of gravity is the point where weight is concentrated, and the base of support is the area bounded by the points where the body contacts the ground. When the center of gravity stays within this base, you remain stable; shift it outside and you risk tipping. Balance relies on sensing position through vision, the vestibular system, and proprioception, then making coordinated muscle actions to keep or restore alignment. This concept underpins steady standing, controlled movements, and safe landings. Coordination, accuracy, and flexibility describe other skills—timing/sequencing of movements, precision of outcomes, and the range of motion, respectively—rather than the specific control of the center of gravity over the base of support.
