Understanding Center of Gravity in Objects

Learn about the concept of center of gravity in objects, how it affects their motion through the air, and why it is important in understanding stability. Explore how the center of gravity differs in symmetrical and irregularly shaped objects and its impact on their movement.

  1. Center of Gravity Section 10.1 Page 136 Brittany McCarter Courtney Schillinger

  2. Baseballs and Baseball Bats • When a baseball bat is thrown, it wobbles and does not flow smoothly through the air. • It wobbles about a special point • It is the sum of two motions: • A spin around this point • And a movement through the air as if all the weight were concentrated at this point. • AKA the center of gravity.

  3. Center of Gravity • The point located at the objects average position of weight. • Symmetrical object • Center • Irregularly shaped object • Center of gravity is toward the heavy end • Objects not made of the same material throughout, have a center of gravity far from the geometric center.

  4. Center of Gravity • When an irregular shaped object is thrown: • it usually rotates around the center of gravity • as well as following a straight line motion with the center of gravity. • No matter where in the air the object is tosses, the center of gravity will always follow a smooth parabola.

  5. Question for the Class • What part of an object follows a smooth path when an object is made to spin through the air or across a flat smooth surface?
