NASA has learned that without Earth’s gravity affecting the human body, weight-bearing bones lose on average 1% to 1.5% of mineral density per month during spaceflight. After returning to Earth, bone loss might not be completely corrected by rehabilitation; however, their risk for fracture is not higher.

There is no correlation between Gravity and aging. Aging is a process that is independent of Gravity. Gravity is a property of matter. Has more to do with atmospheric pressure than the effects of Gravity.

Gravity is very important to us. We could not live on Earth without it. The sun’s gravity keeps Earth in orbit around it, keeping us at a comfortable distance to enjoy the sun’s light and warmth. It holds down our atmosphere and the air we need to breathe.

An object’s center of gravity is the point where the weight is even on all sides. For an evenly shaped object, like a ball or ruler, the center of gravity would be at the middle of the object. For unevenly shaped objects, like you and I, the center of gravity is not quite at the center.

In a subsequent study of infants aged 8 weeks–3 years, it was found that the CG is located even higher on the body (Young, 1968).

The center of gravity is a geometric property of any object. The center of gravity is the average location of the weight of an object. If the object is confined to rotate about some other point, like a hinge, we can still describe its motion. In flight, both airplanes and rockets rotate about their centers of gravity.

Draw a line on the object along the string. For Step 2, repeat the procedure from another point on the object You now have two lines drawn on the object which intersect. The center of gravity is the point where the lines intersect. This procedure works well for irregularly shaped objects that are hard to balance.

Balance the hanger from a corner with the string. Again, allow the mass to hang down and trace a line along the string. Now balance the other corner while holding the string and repeat the tracing. The point where all three lines intersect is the center of mass for the hanger.

Drawing a line along the plumb line enables us to see the vertical line between the hanging point and the centre of the earth. This is why we hang the shape at a different point and draw another line along the plumb line. The intersection of the two plumb lines is the object’s centre of gravity.

To calculate the center of gravity, divide total weight distance moment by total mass of the system. Thus, the center of gravity is 13 meter from left-hand side.
