3.4 Projectile Motion – College Physics

Projectile motion is the motion of an object thrown or projected into the air, subject to only the acceleration of gravity. The object is called a projectile, and its path is called its trajectory.The motion of falling objects, as covered in Chapter 2.6 Problem-Solving Basics for One-Dimensional Kinematics, is a simple one-dimensional type of projectile motion in which there is no …

Motion Characteristics of a Projectile - Physics Classroom

Projectiles are objects upon which the only force is gravity. Gravity, being a vertical force, causes a vertical acceleration. The vertical velocity changes by -9.8 m/s each second of motion. On the other hand, the horizontal acceleration is 0 m/s/s and the projectile continues with a constant horizontal velocity throughout its entire trajectory.
