# Why don't all the bodies accelerate as all of them are brought into motion through a force?

Like in a Projectile, why isn't there an acceleration in the horizontal direction? I've seen things like there isn't any force acting (in the horizontal direction) but for the body to move there must have been some force that caused the motion and by that force there must be some acceleration! So plz someone explain me the real deal!

• @PriyanujBora the horizontal component becomes zero, but not the vertical component (which is just equal to $g$). – Allure Oct 16 '19 at 6:47
