Do the center of the gravity always coincide with the geometrical center of the object?
Only if the object is homogeneous, i.e. the mass is uniformly distributed. If the object is lumpy, or has thick spots and thin spots, then the center of gravity isn't related to the geometric shape.
Consider a see-saw with a light kid on one end and a heavy kid on the other end. The geometric center is the mid-point of the board, but the center of gravity is closer to the heavy kid.

Do the center of mass and the center of gravity coincide?
Yes . If the center of pressure, for the vehicle as a whole, is not located behind the center of gravity (away from the direction of the flight path), then the vehicle will have unstable motion and can tumble. Adding fins to the rear of the vehicle (or increasing fin surface area) will move the center of pressure aft, affording stable flight. A similar effect can be produced by adding weight to the front of the vehicle.
What is the center of gravity for a spherical object?
The center of gravity for a spherical object is located at the exact center of the sphere. This point is equidistant from all points on the surface of the sphere, making it the point where the force of gravity can be considered to act on the object.
Is center of mass the same as center of gravity?
No, they are not the same. The center of mass is the point where the entire mass of an object can be considered to be concentrated, while the center of gravity is the point where the force of gravity appears to act on the object. The center of mass and center of gravity may coincide under certain conditions, such as in a uniform gravitational field.
Where is the center of gravity for a circular bangle?
The center of gravity of a circular bangle is at the geometrical center of the bangle, which is also the center of the circle. This point is equidistant from all points on the circumference of the bangle, making it the point where the weight of the bangle can be considered to act.
Where does an object center of gravity always lie?
It is always different depending on the object. For example a female humans' center of gravity is in the hip. as a male humans' center of gravity is in the chest. But once you have found the center of gravity in an object the center of gravity should be the same in every object like it.
Who found out the geometrical center of gravity?
Newton.
Under what condition the center of mass does not coincide with the center of gravity?
If the gravity is not constant over the body.
Why does the center of gravity and center of buoyancy always not in same position?
Center of gravity is supposed to act at the centroid of the body. while center of buoyancy is the center of gravity of fluid displaced . so they cant be at single point. if the body is completely submerged and homogenous then both cg and cb will coincide
Do the center of mass and the center of gravity coincide?

A similar effect can be produced by adding weight to the front of the vehicle.
Where is the center of gravity of a magnet and coin?
The center of gravity of a magnet is typically in the middle of the magnet, where the mass is evenly distributed. For a coin, the center of gravity is near the geometrical center as long as the mass is evenly distributed.

Difference between center of mass and center of gravity?
The center of mass is a geometrical measurement not considering the weight distribution. The center of gravity is one location on a particular mass structure where the distribution of weight is the same no matter the direction of the measurement as it pertains to that one particular mass structure.
What will be the period of oscillation of a bar pendulum if center of suspension coincide with the center of gravity?
If the center of suspension coincides with the center of gravity in a bar pendulum, the period of oscillation will be constant, meaning the bar pendulum will not oscillate as the forces acting on it will be in equilibrium. The system will be in a stable position and there will be no oscillations.
What is the main difference between center of mass and center of gravity?
Since gravity is produced by mass, the center of mass is also the center of gravity. The only difference between these two concepts is that mass is a more basic quantity, so the center of mass would also be the center of inertia, as well as the center of gravity. In practice, these terms can be used interchangeably.
