Comments Page 1 Flight of an Arrow In this model the distance an arrow flies in a horizontal direction from the position of the archer, given an initial velocity, is calculated for a number of different launch angles. The archer is assumed to have zero height! And the ground is assumed to be perfectly horizontal pl Note that if the launch angle is 0 (the arrow is fired horizontally) the distance it travels is 0; and if the arrow is fired straight up (launch angle 90) the distance it travels is also zero. Notice that the  arrow travels the greatest distance if the launch angle is 45 degrees. The workbook demonstrates the use of a number of new spreadsheet features. Firstly, parameters of the model are entered on a separate worksheet (called the Parameters sheet) given names (in this case g for the gravitational constant, and V for the initial velocity of the arrow,

Do not change the gravitational constant - that is constant throughout the (known) Universe! Secondly, a graph is incorporated into the Trajectory worksheet. Graphs are clearly very useful for visual presentation of information.
