CENTER OF MASS
Center of mass (or center of gravity) = average location of the total mass of the body.
2
The weight force is applied at the center of mass, so center of mass = “center of gravity”.
Location of the c.m.
Balance method:
Suspension method:
3
Location of c.m. of a person
Mathematical model method (or segmentation method): Next lab
Some important points
The c.m. is not fixed to any given part of the body.
The c.m. does not have to be within the material of the body.
4
In airborne motions:
If one part of the body goes down, another must go up as a compensation.
