What are 2 key components of body mechanics?

• A. Center of gravity and Base of Support
• B. Endurance and Strength
• C. Speed and Agility
• D. Flexibility and Balance

Answer: (A)

Stability in body mechanics comes from understanding where your weight is centered and the area that touches the ground. The center of gravity is the point where your body's mass effectively concentrates; its position shifts with your posture. The base of support is the contact area between your body and the ground, which grows when you widen your stance or plant your feet more firmly.

To stay balanced, your center of gravity should stay over the base of support. When it does, movement remains controlled with less effort and the risk of tipping is reduced; if the center shifts beyond the base, balance is harder to maintain. For example, keeping a load close to your body and bending your knees lowers and centralizes the center of gravity, helping it stay well within your base of support.

These two concepts—center of gravity and base of support—form the foundation of body mechanics because they directly govern stability during any movement. Other qualities like endurance, strength, speed, agility, or flexibility influence performance, but they don’t define the core mechanical basis of balance as directly.
