Center of mass and center of area

Click For Summary
SUMMARY

The center of mass and center of area are distinct concepts in physics and geometry. For bodies with constant density, these two centers coincide because the mass distribution is uniform. However, for non-constant density bodies, the center of mass shifts towards regions of greater mass concentration, leading to a divergence from the geometric center. This difference is crucial for understanding balance and stability in physical objects.

PREREQUISITES
  • Understanding of basic physics concepts, particularly mass and density
  • Familiarity with geometric principles related to centroids
  • Knowledge of balancing techniques in physical objects
  • Basic mathematical skills for calculating centers of mass
NEXT STEPS
  • Research the mathematical formulas for calculating the center of mass in non-uniform density objects
  • Explore the implications of center of mass in engineering applications
  • Study the relationship between center of mass and stability in physical systems
  • Investigate the concept of centroid in various geometric shapes
USEFUL FOR

Students of physics, engineers, and anyone interested in the principles of balance and stability in physical objects.

what is the difference between center of mass and center of area ??

i know that they are the same for an constant density body but why ?and why they are different for nonconst density body??

thank u ,,​

The center is a geometric center, the center of mass is where the mass is balanced. Think about your pencil or pen, usually the eraser and that metal on the end is a little bit heavier, so if you want to balance it you need to have your finger slightly towards it and not in the geometric center, hence its center of mass is where its balanced.
 
thank u
