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

Is a projectile one-dimensional?

Projectile motion is the motion of an object thrown, or projected, into the air, subject only to the force of gravity. The object is called a projectile, and its path is called its trajectory. The motion of falling objects is a simple one-dimensional type of projectile motion in which there is no horizontal movement.

Is projectile motion 1d or 2D?

Projectile and circular motion are examples of two dimensional motion.
