What is your understanding of the definition of "center of mass?" Can you provide a general equation for the location of the center of mass of a system of particles?Avaron Cooper said:
It's appropriate to search for that sort of thing on the web rather than ask on a forum. That said, some of the definitions I see out there are not very good. This one is ok: https://en.m.wikipedia.org/wiki/Center_of_massAvaron Cooper said:
How did you think you were going to solve a problem involving center of mass if you don't even know it's definition?Avaron Cooper said:
I know what the center of mass is but I don't know any equation to find the center of mass. If I am going to find the center of mass I would take the torques and find it.Chestermiller said:
Momentum is additive. The momentum of the whole system is equal to the sum of the momenta of its component parts. So yes, if there are two pieces and one is stationary (zero momentum) then the momentum of the combined system is equal to the momentum of the other piece alone.Avaron Cooper said:
The center of mass is a point in an object or system of objects where the mass is evenly distributed and the object or system behaves as if all the mass is concentrated at that point.
The center of mass can be determined by finding the average position of all the mass in the object or system. For a uniform object, the center of mass is located at the geometric center. For an irregular object, the center of mass can be found by balancing the object on a point or by using mathematical equations.
The center of mass is significant in Newton's laws of motion because it is the point where the force of gravity acts on an object or system. This is important because it allows us to predict how the object or system will behave when subjected to external forces.
The lower an object's center of mass is, the more stable it is. This is because a lower center of mass means that the object is less likely to topple over when subjected to external forces, such as a push or pull.
Yes, the center of mass can be outside of an object if the object is not uniform. For example, in a soccer ball, the center of mass is located at the center of the ball, even though the mass is not evenly distributed throughout the ball.
