Center of Gravity vs. Center of Mass
The center of gravity is usually based on the weight; on the contrary, the center of mass is generally based on mass. The center of gravity is considered as the point where the complete weight of the body is suspended; on the other hand, the center of mass is considered as the point at which complete body mass is assumed to be focused. Around the center of gravity, the weight distribution of the body is uniform; on the contrary, around the center of mass, the mass distribution is considered uniform.
Through the center of gravity, if an object passes an axis, then the weight which is acting to the left becomes equal to the weight acting at the right side; on the flip side, through the center of mass, if an object passes an axis, then the mass which is acting at the left side becomes equal to the mass which is acting at the right side. The center of gravity usually changes with the change occurs in the force of the acting gravity of the earth and moves closer to the regions of the object in a stronger field; on the other hand, the center of mass rests unaffected with the change occurs in the gravitational field.
The net torque because of gravity about the point of the center of gravity is zero; on the flip side, the center of mass would give some angular momentum when spinning about that point. The center of gravity depends on the gravitational field; on the contrary, the center of mass does not usually depend on the gravitational field. If the gravitational field power is stronger in the direction of feet and weaker near the head, then the center of gravity would be present around knees or below the center of mass; on the other hand, if gravitational field power is stronger near the head and weaker in the way of the feet, the center of mass would be present around shoulders or above the center of gravity.
The center of gravity is the vertical measurement, whereas the center of mass is more consideration of a horizontal measurement. The center of gravity is the weighted normal of place concerning mass intervals local g; on the other hand, the center of mass is the weighted normal of place concerning mass.
What is the Center of Gravity?
The center of gravity is defined as the specific point present in a body around which the instants because of the force of gravity considered zero. The center of gravity is the place where the whole of the body could be perfectly balanced against gravity. If that specific point is provided with support contrary to gravity, then the body will become in the equilibrium position.
C.G. or simply G is used to denote the center of gravity. The center of gravity could be present inside or outside of the body of the object. The center of gravity always depends on the gravitational field (g) because when the value of gravitational field changes, the value of the center of gravity will also change in corresponds to the change in the gravitational field. The position of the center of gravity could be found by this. If the gravitational field power is stronger in the direction of feet and weaker near the head, then the center of gravity would be present around knees or below the center of mass.
What is the Center of Mass?
The center of mass is defined as the place where the relative position of the mass is calculated as zero. Around the center of mass, the mass distribution is considered uniform. The center of mass does not depend on the gravitational field (g), so the body rests unaffected with the change in the force of the gravitational field.
The center of mass is present at the center or centroid in case of simple rigid objects having a uniform density. In the case of complicated objects, the center of mass from all parts becomes zero. The center of gravity is useful in solving mechanical problems. The center of mass could be found if gravitational field power is stronger near the head and weaker in the way of the feet, the center of mass would be present around shoulders or above the center of gravity.
