Question

distinguish between center of mass and cneter of gravity grcshjnnan​

Answer 1

Explanation:

1. The center of mass is defined as the distribution of mass in space. In center of mass, the objects are weighed and divided according to their masses. On the other hand, the center of gravity is defined as a point at which the object acts in response to gravity.

Answer 2

Answer:

1. Centre of mass of a body is that point at which entire mass of the body can be assumed to be concentrated for describing the translatory motion of the body. while centre of gravity of a body is that point at which entire weight of the body can be assumed to be concentrated for describing translatory motion.

2. The mass of body remains constant and is independent of its position while weight depend on acceleration due to gravity which depends on position of body.

3. If body lies near the surface of the earth and its constituent particles are not largely separated, the the value of g can ve assumed to be constant for all the particles of the body. In such case, COM and COG will coincide each other.( Only if body is of small size)
