Can anyone give me an object where the center of mass and the center of gravity are in different locations?
Because the gravitational field is not uniform: It's stronger the closer you are to the spherical object, so the lower half is pulled more strongly than the upper half. Since the field falls off inversely with the square of the distance, the farther away you are the less it matters.texasratt said:why is it below and why does this get smaller with distance?
The center of mass is the point at which an object's mass is evenly distributed, while the center of gravity is the point at which an object's weight is evenly distributed. In most cases, these two points are the same, but in cases where there is a significant difference in gravitational pull, such as near a black hole, the center of gravity may differ from the center of mass.
The center of mass/gravity can be calculated by finding the weighted average of an object's individual parts. This is done by multiplying the mass of each part by its distance from a chosen reference point, and then dividing the sum of these products by the total mass of the object.
The center of mass/gravity is important because it helps us understand how an object will behave when subjected to external forces. It also helps engineers design stable structures and vehicles, as well as helps athletes and dancers maintain balance and control.
No, the center of mass/gravity must always be located within the boundaries of an object. However, in some cases, it may appear as though the center of mass/gravity is outside of the object, such as in a leaning tower, but this is due to the distribution of mass within the object.
The center of mass/gravity can change depending on the shape and distribution of mass in an object. For example, a solid sphere has its center of mass at its geometric center, while a hollow sphere's center of mass is closer to its outer surface. Generally, objects with more mass towards the bottom have a lower center of mass/gravity, making them more stable.
