An object in projectile motion will follow which path?

curved down toward the ground

Explanation:

A projectile movement is a movement composed of a horizontal movement and a vertical movement. According to Galileo, if an object presents a compound movement, each of the component movements is performed as if the others did not exist and in the same interval of time. This is the principle of simultaneity.

When an object is cast horizontally, it describes a parabolic movement in relation to the Earth. Accordingly, we can conclude that an object in projectile motion will follow a curved path to the ground.
