(A projectile's horizontal velocity remains constant because gravity is a vertical force and no horizontal force acts on the projectile
A projectile's horizontal velocity remains constant because gravity is a vertical force and no horizontal force acts on the projectileNewton's third law states that for every action force there is a reaction pair force.

A propeller airplane works the same way.
