projéteis

Projetis refers to objects or substances that are propelled through space or air, typically by a force. In physics, a projectile is any object that is launched by a force and continues in motion under the influence of gravity and air resistance. The path followed by a projectile is called its trajectory. Understanding projectile motion is fundamental to many scientific and engineering disciplines.

Common examples of projectiles include cannonballs, arrows, bullets, and even thrown balls. The initial velocity and launch angle are critical factors determining the projectile's trajectory, range, and maximum height. The force of gravity acts vertically downwards, constantly accelerating the projectile towards the Earth. Air resistance, or drag, is another force that opposes the motion of the projectile, reducing its speed and altering its trajectory.

The study of projectiles has historical significance, particularly in ballistics, which deals with the motion of projectiles fired from firearms. Modern applications extend to areas like sports science, where analyzing the motion of a ball is crucial for optimizing performance, and aerospace engineering, for understanding the flight of rockets and missiles. The principles of projectile motion are often simplified in introductory physics by neglecting air resistance to focus on the effects of gravity.
