To take a riff on the common comedy bit: How long is a piece of string?
It depends on the composition and mass distribution of your table and your object.

When an object is balanced so that a displacement lowers its center of gravity is it in stable equilibrium?
False
Describe two forces that can affect an objects velocity?
Friction and Gravity are the two forces that affects an object's velocity. Friction is caused by both air and the surface on which an object is moving. Gravity is caused by Earth.
What is the downward pull of a object due to gravity?
The strength of the force in each direction between the earth and any mass is called the "weight" of the mass. The force is equal in both directions, which means that the weight of the mass on earth is the same as the earth's weight on the mass. The force acts along the line between the center of the earth and the center of the mass. The direction toward the center of the earth is customarily referred to as the 'down' direction, and toward the center of the mass as the 'up' direction.
Why a falling object subjected to earth's gravity does not continue to accelerate forever?
It does ! The amount is insignificant. Look at it another way, the moon is always falling toward the Earth ... and the Earth is always falling toward the moon. They are both accelerating.
What are the 2 forces that able an object to stay in orbit?
There are two forces responsible for an object to stay in orbit Namely-- 1-Centripetal Force --Which pulls any object toward the center 2-Centrifugal Force --Which push any object away from the center
What is the scientific definition of gravity?
Gravity: The attraction between an object on the surface and the center of the earth.
The average position of the distribution of the weight of an object is?
Center of gravity is the average position of the distribution of the weight of an object. For objects near the earth's surface, center of gravity is the same location as center of mass. This is because weight and mass are proportional.
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.
Is it possible for an object not to have a center of gravity?
No, but the centre of gravity need not be inside the object. Not unless Gravity is not a variable. But it is not possible for an object to not have a center of mass.
What part of an object follows a smooth path when the object is made to spin through the air or across a flat smooth surface?
The center of gravity.
Can an object have more than one center of gravity?
No, objects cannot have more than one center of gravity. The center of gravity of an object can however change.
Can an object have two center of gravity?
No. The center is the center.
What is the accelaration gravity of the center of Earth Surface?
At the earth's center, the acceleration/force of gravity is theoretically zero.(At least the force of gravity between the earth and an object at its center. There's still the gravitational forcesbetween the object and everything else ... the sun, moon, stars, etc.)
What is the center of gravity for a spherical object?
If the object is homogeneous, its center of mass is in its geometrical center. And if it is small compared to Earth, its center of gravity is, for all practical purposes, its center of mass.
What is the difference between rolling and rotation?
When an object rolls the center of gravity (or of geometry - or both depending on the shape of the object) translates (moves) along a path and there is a point of contact with a surface on the perimeter of the object, rotation (angular change) does occur too.During rotation the center of gravity could be motionless and there is probably no point of contact with any surface; the movement is purely angular.
What are the Factors effecting center of gravity?
The only factor that affects the center of gravity is how the mass of an object is distributed.
How do you predict whether an object will topple dealimg with the center of gravity?
The center of gravity of an object is one factor in determining the stability of the object. The lower the center of gravity, the more stable the object. Other factors must be used for the prediction such as the shape of the base and overall structure.
