The centre of mass of an object is the point where the whole of the object is assumed to be concentrated. Refers to masses or weights. The . centre of gravity . Centre of Gravity. Centre of Mass ~ . CoM. This is a . point. on an object where the total mass acts as if it is concentrated. . Also know as the . centre. of gravity ~ where the weight force acts on an object. Up to this point in the course we have treated everything as a single point in space, no matter the mass, size, or shape. We call this “special point” the . CENTER OF MASS. . The .
