For a projectile launched at an angle, are the forces in the vertical direction balanced or unbalanced?

Unbalanced because of the different forces pulling and pushing in certain directions

Unbalanced as long as it is moving up or down. Immediately after being fired the vertical force from the launch will be greater than the force of gravity. for an instant at the the beginning of the projectiles decent the force will actually be balanced and there will be no vertical movement. After that the force of gravity is greater.

tl; dr they are unbalanced
