Center of Mass Concept Map: Key Ideas Explained
The center of mass is the point where the mass of a body or system is considered to be concentrated for the purpose of describing its motion. For a set of particles it is the weighted average of their positions. For a rigid body it depends on how mass is distributed, and for symmetric objects it lies on the axis of symmetry. A good center of mass map separates these ideas clearly.
- Definition: the mass-weighted average position of a system
- Discrete formula: sum of mass times position, divided by total mass
- Continuous bodies: integrals over volume or density
- Symmetry: where uniform objects have their center of mass
- Applications: stability, balance, rotation and projectile motion
Use the map to revise the formulas, then check each branch against your textbook. Generate a personalized center of mass map from your own notes with CogniGuide.

Center of Mass Questions Answered
Common questions about the topic and about building your own map.
What is the difference between center of mass and center of gravity?
The center of mass is the mass-weighted average position of a body. The center of gravity is the point where the total gravitational force acts. In a uniform gravitational field they coincide, which is why the two terms are often used interchangeably in introductory physics.
Where is the center of mass of a uniform rod?
For a uniform rod it lies at its geometric midpoint. The same is true for a uniform sphere, cube or cylinder, where the center of mass sits at the geometric center because the mass is evenly spread.
Which files can I use to make a center of mass map?
You can upload PDF, Word (DOCX), PowerPoint (PPTX), text or Markdown files, or an image of your notes. You can also skip the upload and type the topic name.
Can I turn my center of mass map into a quiz?
Yes. A finished map can be turned into a quiz to test yourself, and the same notes can be used to make flashcards. A free plan allows 5 creations a week.
