No, objects cannot have more than one center of gravity. The center of gravity of an object can however change.

Is an upward force that either baiances or exceeds the force of gravity?
Any upward force on an object can be less than, equal to, or greater than the force of gravity on that object. It all depends on the object's mass and distance from the center of the Earth.
What is the importance knowing the center of gravity?
if you have a large complex object, like a jar full of different size coins, but know its center of mass then you can make a simplification of the jar to a point of mass at the center of gravity. A point is much simpler to physics on than a whole jar of different coins. in this case it doesn't matter what the object is made of.
Why do airplanes defy gravity?
Airplanes do not "defy gravity", any more than you do when you walk upstairs. In both cases, an upward force is generated that is greater than the downward force of gravity on an object. Since the net force on the object is then upward, the object accelerates upward.
How does gravity vary and why?
Gravity varies depending on the mass of an object and the distance between objects. According to Newton's law of universal gravitation, the force of gravity decreases as the distance between objects increases. Additionally, the greater the mass of an object, the stronger its gravitational pull. This variation in gravity is why objects on Earth feel a stronger gravitational pull compared to objects in space.
What does weight have to do with matter?
Matter is what is in an object...it is what something is made of.Weight is the effect of gravity on an object.The more matter in an object, the greater effect gravity has on that object, making it weigh more than another object with less matter.Don't forget that size does not always show how heavy something is...If you have a small object which is really dense (contains a lot of matter), it may weight more than a larger object with a low density.
How is the force of earth's gravity overcome when an object is launched into space?
The object launched into space has rocket motors with more force taking it away from Earth than Earth's force of gravity has in pulling the object toward its center.
Does the center of gravity always lie on the body?
The center of gravity always lies within an object, and is the location at which the entire mass can be considered acting at a single point.For a system of more than one object, the center of gravity can lie anywhere between the farthest points of the objects, depending on the distribution of mass. The center of mass is called the barycenter.
Is an upward force that either baiances or exceeds the force of gravity?
Any upward force on an object can be less than, equal to, or greater than the force of gravity on that object. It all depends on the object's mass and distance from the center of the Earth.
Which is the force that pulls objects toward centre of the earth?
The force that pulls an object toward earth also pulls the earth toward the object.The two forces are equal. Together, we refer to them as the force of gravity.Isaac Newton developed this concept.Gravity. The Earth has more mass than the object, it pulls it towards its' center.
Which best explains why the weight of an object is less at the equator than at the poles?
The earth is not a perfect sphere. The spin of the earth causes it to buldge out at the equator, which means the equator is further from the center of the earth then the poles are. The further an object is from the center of mass of another object, the less effect the gravity of those objects will have on each other. So at the equator, an object is being effected less by the gravity of the earth then it is at the poles.
Why is gravity stronger at the poles than the equator?
The closer an object gets to the center of the earth, the greater the pull of gravity on that object.

Does a more massive object weigh more than less massive one?
If the force is gravity, the answer is yes. Gravity "pulls" on an object in proportion to its mass. A heavier (more massive) object is pulled on by gravity more than a lighter (less massive) object. A football tackle is pulled on by gravity more than the average grade school student.
How is the force of earths gravity overcome when an object is launched into space?
When on Earth, you can escape if you move away from the Earth at the "escape" speed. Gravity will slow you down and you will reach zero speed at an infinite distance.
Is there gravity under the seas and ocean?
The effect of gravity is what makes objects that are more dense (mass per unit of volume) than water, like rocks, sink to the bottom. Objects that have less density than water will float because their bouyancy is stronger than the force of gravity.
Does the earths gravity pull the moon more than the moon pulls the earth?
Yes.. Always gravity exerted by an object that has larger mass is more.
