Projectile motion refers to the motion of an object that is launched into the air and moves along a curved path under the influence of gravity. It is a fundamental concept in physics and is often encountered in various real-life situations.

When an object is in projectile motion, its path is called a trajectory. The trajectory depends on the initial velocity of the object and the angle at which it is launched. For example, when a ball is thrown into the air at an angle, it follows a parabolic trajectory.

The range of a projectile refers to the horizontal distance it travels before hitting the ground. It is influenced by both the initial velocity and the launch angle. Higher initial velocities or launch angles tend to result in greater ranges.

In projectile motion, the key components to consider are the horizontal and vertical components. The horizontal component remains constant throughout the motion, while the vertical component is affected by the force of gravity. Understanding these components is crucial for analyzing and solving projectile motion problems.
