Centre of Mass and Centre of Gravity
Usually, gravity is assumed to be a uniform force acting on the body. In that case, the centre of mass and centre of gravity are almost the same thing but as we change the force of gravity to be non-uniform, then the position of both points changes and we have different centres of mass and centre of gravity for an object in a non-uniform gravitational field.
Centre of Mass
Centre of Mass is the point of anybody where all the mass of the body is concentrated. For the sake of convenience in Newtonian Physics, we take the body as the point object where all its mass is concentrated at the centre of mass of the body. The centre of mass of the body is a point that can be on the body such as in the case of a Circular sheet, rectangle sheet, sphere, etc, and can also be outside the body such as in the case of a ring, hollow sphere, etc.
In this article, we’ll explore the basic fundamentals of the centre of mass, including its definition, methods, and formula to calculate it. We’ll also discuss some real-world examples of the centre of mass to help you see its practical applications. So, let’s start learning about the fascinating world of the centre of mass and its role in the physics of motion.
