Question

mention any 4 characteristics of centre of mass

Answer 1

$<b><I>$
here's your answer

FOLLOWING ARE THE CHARACTERISTICS OF CENTRE OF MASS :

1) the centre of mass of a system of particles depends only on the masses of the particles and their relative positions .

2) son of moments of masses of the system about centre of mass is zero

3) for a continuous distributed mass object it depends on the shape and its mass distribution

4) a mass particle need not be present at the position of the centre of mass

5) the location of centre of mass is independent on the references free used to locate it

6) the centre of mass Mail live within the body or outside material of the body but it should be present within the boundaries of the system

Answer 2

The following are the features of the center of mass:

1. The coordinate system used does not affect the position of the center of mass. A body's center of mass might be located either within or outside the body.
2. Internal forces do not affect the location of the center of mass. External factors alone can cause the center of mass to shift.
3. The center of mass is always on the axis of symmetry if the body has one. The point of intersection is where the center of mass of a body having two or more axes of symmetry is located. The system's center of mass may or may not correspond with any of the particles in an N-particle system.
4. The center of mass is a hypothetical spot where the body's total mass is thought to act. The position of the center of mass is independent of the free references used to locate it. The center of mass might be found within or outside of the body, but it must remain inside the system's boundaries.
