In this section, we're going to look at a Python program that uses turtle graphics to play a simple game. The object of the game is to launch the turtle like a projectile so it hits
the target. You do this by entering an angle, and a force value in the Shell window. The program then sets the turtle's heading to the specified angle, and it uses the specified
force value in a simple formula to calculate the distance that the turtle will travel. The greater the force value, the further the turtle will move. If the turtle stops inside the
square, it has hit the target.
