What is the center of mass?
Quick Answer
The center of mass is the average location of all the mass in an object or system. It is the point that moves as if all the mass were concentrated there.
The Full Story
The center of mass is a useful simplification in physics and engineering. For a symmetrical object of uniform density, it lies at the geometric center, but for an irregular shape it may be elsewhere, even outside the material itself. Motion of systems such as thrown objects, satellites, and athletes can often be understood by tracking the center of mass. It is also crucial in balancing and stability. In a gravitational field, the center of mass and center of gravity are often close together, though not always identical.
