What Is The Centre Of Gravity?

Answer Question

1 Answer - Sort by: Date | Rating

    The centre of gravity of a body is the point where the whole weight of the body can be considered to act. The centre of gravity of a body may even lie outside the actual material of the body. For example, the centre of gravity of a ring lies at its centre, which is outside its material.

    The stability of an object is connected with the position of its centre of gravity (CG). If the vertical through the CG passes through the base of an object, then it is stable, otherwise it is unstable and topples down. Bodies with low CGs and wide bases are more stable.

    Racing cars are built low and with wide wheelbases to reduce the risk of overturning at sharp bends.

    While crossing a river in a boat, passengers are not allowed to stand. This keeps the CG of the system (boat and passengers) low and ensures stability.
