Gravity
What is gravity? The value of gravity (g) is 32 ft/s2 (feet per second squared) or 9.8 m/s2 (meters per second squared). This value is a constant, which means that all objects fall to the earth at the same rate of acceleration, no matter how much they weigh (there is some slight variation in the value for g depending where on earth you are located). Read about a Gravity Experiment with a bowling ball.
What is Center of Gravity (CoG)?
The Center of Gravity (CoG) is the point at which gravity can be considered to act. In most cases (with uniform gravity) it is equal to the center of mass. The CoG is not always within the object, as in the case of unusually shaped objects.
Center of Gravity in bowling
Bowling pins have a low center of gravity due to their shape, which make them more stable. The center of gravity of a bowling ball is not always in the absolute middle of the ball. The position of the center of gravity is usually indicated by the position of the logo or punch mark onthe surface of the ball.
