Additionally, the object will also usually have a launch angle, starting from $\theta=0$ on the positive $x$ axis. There are generally 2 methods to go about this, with one being a substitution of gravity into another. ### General Projectile Vectors for Constant Acceleration Without any further definitions, other than $\vec{v}$ is the velocity vector, $\vec{a}$ is the acceleration vector, and $\vec{s}$ is the position vector. The velocity vector is a function of any given point of time $t$ given as such:
