    Gravity produces a constantacceleration that acts on the

    projectile from release to

    landing, causing the projectile to

    follow the path of a parabola.

    Determining Factors

    Release velocity

    Release angle

    Release Point

    The ball follows a path that

    is a tangent to the release

    point on the arc of the

    throwing motion.
