Homework Statement
Now, I know the centre of gravity can change depending on how close to uniform the gravitational field is, and it is where the weight appears to act from.
But, what is the centre of mass? Ok, it is a constant; doesn't change; and in an uniform gravitational field the two centres overlap; but how do you define the centre of mass without referencing centre of gravity?
An online source said it is the point from which the mass is 'equally distributed in all directions' for an object; but I can have irregular shapes. What does that source means? Or is the centre of mass defined in another way?
I am really confused!
Thanks in advance for any help you could provide :)
