<p><P>PROBLEM TO BE SOLVED: To intuitively and clearly show an object person such as a golfer the relation between the carry of a flying object such as a golf ball and factors to determine the carry. <P>SOLUTION: The carry chart, on which iso-carry lines of a golf ball at a prescribed speed of the head of a golf club are indicated on a two-dimensional coordinate space, is provided. In this case, the "iso-carry line" is a curve or continuous straight line indicating the equal carry such as a contour line indicating the equal height of a mountain, etc. or an isobar indicating the equal pressure. The rotational frequencies of the golf ball are indicated in the X-axis, and the hitting angles of the golf ball are indicated in the Y-axis. The rotational frequency of the golf ball means the quantity of backspin in this case. <P>COPYRIGHT: (C)2004,JPO</p> |
