Study Notes
Center of Mass
- The center of mass of a distribution of mass in space is a point where the entire mass of the system can be considered to be concentrated.
Importance of Center of Mass
- The center of mass is a useful reference point in mechanics because it simplifies the analysis of motion and allows us to treat complex systems as a single particle.
Location of Center of Mass
- In a single rigid body with uniform density, the center of mass is located at the geometric center of the body.
- The center of mass can be located outside the physical body, such as in the case of a ring or a hollow sphere.
Representation of Center of Mass
- The center of mass represents the average position of the mass of an object, and it is the point that moves in response to the net force acting on the object.
