FINALE Fireworks User Guide
The Shell body controls let you fine-tune the shell’s mass, such that the shell is more or less susceptible to air
friction, gravity, and wind. These attributes only affect the shell’s trajectory; they don’t modify the size or
appearance of the shell. Also, the Shell body values that you set here don’t affect the similar values in the Star
body tab. If you want to make similar changes to both the shell and its stars, you have to visit both tabs.
Name
Weight
Attribute
Slider (Scaler; 1.0 = natural weight)
Sets the shell’s weight. A value of 1.0 is the shell’s “natural” weight. If you increase the value, the shell
becomes heavier and is pulled back to Earth more quickly. Smaller values make the shell lighter and so the
upward portion of its trajectory is less affected by gravity.
Momentum
Slider (Scaler; 1.0 = natural momentum loss)
As a shell consumes its pyrotechnic material, it loses mass and momentum, and thus slows down and
becomes increasingly more susceptible to the effects of the wind and air friction. This attribute lets you set
the scale of the shell’s ultimate momentum (the point at which it has exhausted its material) compared to its
launch momentum. A value of 1.0 produces a “natural” momentum loss. If you increase the value, the shell
maintains more of its momentum over the course of its trajectory. If you decrease the value, the shell loses
momentum more quickly.
Wind resistance
Slider (Scaler; 1.0 = natural wind resistance)
Sets the shell’s susceptibility to the wind and air friction. A value of 1.0 produces a slight, natural resistance.
Decreasing the slider’s value makes the shell less affected by the wind, causing its trajectory to straighten
and elongate. Increasing the value increases the effect of the wind and air friction on the shell, shortening its
trajectory and bending it in the direction of the wind.
