The centre of gravity is the point at which the weight of an object can be considered to be concentrated and acts as the single point of balance for the object.
The centre of gravity of a line can be determined by finding the midpoint of the line. This is the point where the weight of the line is evenly distributed on both sides, making it the centre of gravity.
The length and weight distribution of the line are the main factors that affect the centre of gravity. The longer the line, the more it will shift towards the middle, and the heavier the line, the more it will shift towards the heavier end.
The centre of gravity is important in physics because it helps determine the stability and balance of an object. The lower the centre of gravity, the more stable the object is, and the higher the centre of gravity, the more prone it is to tipping over.
Yes, the centre of gravity can be outside of the object if the object is irregularly shaped or has a non-uniform weight distribution. In this case, the centre of gravity may be located at a point outside of the physical boundaries of the object.
