what is the difference between center of mass and center of gravity ? please explain it in an easy way ...
The center of mass is the point in an object where its mass is equally distributed in all directions. The center of gravity is the point where the force of gravity appears to act on an object. In most cases, the center of mass and center of gravity are at the same point, but there are certain cases where they may differ, such as when an object is in a non-uniform gravitational field.
The center of mass of an object can be determined by finding the point where the object would balance if suspended from that point. It can also be calculated mathematically by dividing the sum of the individual masses of the object by the total mass of the object and multiplying it by the distance of each individual mass from a reference point.
The shape of an object can affect its center of mass. For example, an object with a symmetrical shape will have its center of mass at its geometrical center. However, for asymmetrical objects, the center of mass may be closer to the denser or larger side of the object.
Yes, the center of mass can be outside of an object. This can happen when an object is composed of multiple parts with different masses and distribution of mass. In such cases, the center of mass may be located in the empty space between the parts.
The position of the center of mass affects an object's stability. If the center of mass is located above the base of support, the object will be stable. However, if the center of mass is outside the base of support, the object will be unstable and will topple over. This is why it is important to consider the center of mass when designing structures or balancing objects.
