| Physicists love to look at something complicated and find in it, something simple and familiar. Here is an example. If you flip a baseball bat into the air, its motion as it turns, is clearly more complicated than that of a non-spinning tossed ball, which moves like a particle. Every part of the bat moves in a different way from every other part. It is a system of particles. But if we look closely, we find that one point of the bat moves in a simple parabolic path. That is nothing but the centre of mass. |

| What is the importance of knowing the centre of mass of an object? Once we know the centre of mass of a body, one can balance the body by placing a support exactly beneath the point. |
