That sounds really logical, because that is a good way to think about how balance works, but it’s not that useful – because where is the centre of gravity? The . With that being said, this constant force put’s pressure through our body, from the top of our head down to the floor.
Gravity, therefore, provides a passive extension torque at the hips, which, if not opposed, would cause backward bending of the pelvis over the femurs. Inilah titik tempat objek dalam keadaan seimbang sempurna, tanpa peduli bagaimana objek diputar atau dibalik pada titik tersebut. Center of gravity can be affected by weight, weight distribution, and position. Any movement of the line of gravity in any direction except along the line of support will result in a loss of balance.
