# Center of Gravity vs. Center of Mass

Main Difference

The main difference between Center of Gravity and Center of Mass is that the Center of Gravity is the point where complete bodyweight becomes balanced, whereas the Center of Mass is the point where the complete mass of the body becomes concerted. Center of Gravity vs. Center of Mass — Is There a Difference?

## Difference Between Center of Gravity and Center of Mass

#### Center of Gravity vs. Center of Mass

Weight is considered as the main point on which center of gravity is based; on the contrary, mass is considered as the main point on which the center of mass is based.

#### Center of Gravity vs. Center of Mass

The distribution of the bodyweight is uniform nearby the center of gravity; on the contrary, the distribution of the mass body is uniform nearby the center of mass.

#### Center of Gravity vs. Center of Mass

Vertical measurements are mainly taken in the center of gravity, whereas the center of mass is taken more in horizontal measurements.

#### Center of Gravity vs. Center of Mass

The center of gravity is determined by the gravitational field; on the contrary, the center of mass does not usually determine by the gravitational field.

#### Center of Gravity vs. Center of Mass

The weight which is acting to the left horizontal of the point of normal becomes equal to the weight acting at the right side of the point of normal when an object passes through the axis of the center of gravity; on the flip side, the mass which is acting at the left side of the object’s normal point usually becomes equal to the mass which is acting at the right side of the object’s point of normal when an object passes through the axis of the center of mass.

#### Center of Gravity vs. Center of Mass

When some changes occur in the earth’s acting gravity force then the center of gravity changes according to it and moves closer to the object in regions where a stronger field is present; on the other hand, gravitational does not have any effect on the center of mass, and it remains unchanged.

#### Center of Gravity vs. Center of Mass

The net torque is zero in the center of gravity due to the normal point of the center of gravity; on the flip side, the center of mass will offer some angular momentum when rotating about the point of normal.

#### Center of Gravity vs. Center of Mass

The center of gravity would be existing nearby knees or below the center of mass if the gravitational field strength is powerful in the direction of feet and weaker near the head; on the other hand, if gravitational field strength is powerful near the head and weaker around the feet, the center of mass then will be present nearby shoulders or directly above the center of gravity.

## Comparison Chart

 Center of Gravity Center of Mass The center of gravity is the place at which the circulation of weight is the same in all directions. The center of mass is the place at which the sharing of mass is the same in all directions. Based On Based on the weight Based on the mass Considered As It is considered as the point where the complete weight of the body is suspended. It is considered as the point at which complete body mass is assumed to be focused. Uniform Distribution The weight distribution of the body is uniform. The mass distribution of the body is uniform. Variation When Passes an Axis If an object passes an axis, then the weight which is acting to the left becomes equal to the weight acting on the right side. If an object passes an axis, then the mass which is acting at the left side becomes equal to the mass, which is acting on the right side. Effects of Change Usually, changes with the change occur in the force of the acting gravity of the earth and move closer to the regions of the object in a stronger field. Rests unaffected with the change occurs in the gravitational field. Net Torque/Angular Momentum The net torque because of gravity is zero. Give some angular momentum when spinning about that point. Dependence on Gravitational Field It depends on the gravitational field. It does not depend on the gravitational field. Position of Gravity According to the Body 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. 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.

### 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.

Conclusion

Above discussion concludes that the center of gravity is the point where the entire body mass becomes even or equal, and it depends on the gravitational field, whereas the center of mass is the point where the entire mass of the body becomes combined or collective, and it does not depend on the gravitational field.
