2 Example 7-12 A group of extended bodies, each with a known CM. Find the CM of the group.

3 Center of Gravity Center of Gravity (CG): Similar to Center of Mass. CG  That point in extended body at which force of gravity may be considered to act. For practical purposes, CG = CM.

4 Application to The Human Body
Approximate as a collection of particles at various CM points

5 Example 7-13  CM is outside the body!
Use the Table!! Can have the CM outside of the body!  CM is outside the body!

6 Conceptual Example 7-14

Center of Mass. Up to now, we’ve been mainly concerned with the motion of single (point) particles. To treat extended objects, we’ve implicitly approximated.
