The capacitor is charged by connecting it to a voltage source. The amount of charge stored in the capacitor determines the potential energy available for the launch.

Aiming

The launcher is equipped with an adjustable angle and height mechanism that allows the user to aim the projectile at a specific target.

Firing

When the trigger is pulled, the capacitor discharges its stored energy through a coil, creating a strong magnetic field. This magnetic field interacts with the metal projectile, propelling it forward.

Factors Affecting Trajectory and Distance

The trajectory and distance of the projectile are influenced by several factors, including:

• -*Initial velocity

  The initial velocity of the projectile is determined by the amount of charge stored in the capacitor.

-*Angle of launch

The angle at which the projectile is launched affects its trajectory and distance.
