Projectile motion is an example of what kind of motion

Projectile motion is a form of motion experienced by an object or particle (a projectile) that is thrown near the Earth's surface and moves along a curved path under the action of gravity only (in particular, the effects of air resistance are assumed to be negligible). Therefore its circular 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.
