A projectile launcher is a device designed to propel objects, known as projectiles, through the air. These launchers can vary in size and complexity, ranging from simple slingshots to advanced military systems like catapults and ballistic missiles. They operate on principles of physics, utilizing force to achieve motion and distance. Projectile launchers are used in various fields, including sports, entertainment, and military applications. In sports, devices like bowling machines help players practice their skills, while in the military, launchers are crucial for delivering munitions accurately. Understanding their mechanics is essential for improving performance and safety.
