The center of gravity is the point at which the entire weight of an object can be considered to act. It is the point where the force of gravity on an object is balanced in all directions.
The center of gravity of an irregularly shaped object can be determined by suspending the object from different points and marking the plumb line. The intersection of these plumb lines is the center of gravity.
Yes, the center of gravity of an object can change if the distribution of weight within the object changes. For example, if more weight is added on one side, the center of gravity will shift towards that side.
The center of mass is the point at which the total mass of an object is considered to be concentrated. It takes into account both the weight and the distribution of mass within an object. The center of gravity only considers the weight of the object and its distribution.
Knowing the center of gravity of an object is important for stability and balance. If the center of gravity is too high or too low, an object may be more prone to tipping or falling. It is also important in engineering and design to ensure that an object is properly supported and can withstand external forces without collapsing.
