Center of mass physics equations
WebThe center of mass (or CM) is defined to be the position Like any vector equation, this represents separate equations for each of the components (X, Y, Z): You can think of the center of mass as a weighted average of the positions of each mass element, i.e. weighted by the mass of that element, or equivalently it is the vector sum of the ra, each … Web(i) To find center of mass from the origin: The point masses are at positions, x 1 = 4 m, x 2 = 8 m from the origin along X axis. The center of mass x CM can be obtained using …
