Question

Centre of gravity of semicircle simple explanation

Answer 1

Hi friend here is your answer

The point that is in the exact center of a shape or object is known as the centroid. If the object has a uniform density, then the centroid is also the center of mass, which is the point at which the object will balance with just as much mass on all sides.

Just like the pencil, you also have a center of mass, and you have to be careful to keep it directly over your feet or you'll lose your balance too! To see how this works, stand up with your back against a wall and try to lean forward until you touch the floor. You will find that you can't do it without falling over! This happens because as you lean forward, your center of mass moves further and further in front of your body until it's not over your feet anymore, and you lose your balance, just like the pencil does if you don't balance it exactly at the center of mass.
