This happens because the spinning motion comes from another property known as the moment of inertia (sometimes abbreviated as “moment,” but not to be confused with torque). But what if you were holding the baseball by one of its sides? It would spin as it fell. For instance, if you hold a baseball in your hand and let go, the ball will fall straight down due to gravity acting on its center of gravity. This “single mass” is called the object’s center of gravity, and it determines how the object will move. Standing waves in strings and organ pipes, fundamental mode and harmonics- beats.When we think of an object moving through space, it’s easy to imagine a single mass at its center.
