Projectile motion is an example of what kind of motion

Projectile movement is an example of what kind of two-dimensional movement.

Explanation:

We call the movement of projectiles to the free movement of a body launched in a uniform gravitational field, where the acceleration of gravity is constant and vertical, the air resistance being negligible. This movement is considered a two-dimensional movement, because when we launch a projectile, its movement can always be decomposed into two movements, one horizontal and one vertical.

The horizontal movement will be uniform since there is no acceleration with a horizontal component, that is, the horizontal component of the projectile speed is constant.

The vertical movement will be uniformly varied with an acceleration equal to that of gravity.
