The figure represents the parabolic trajectory of a ball going from a to e in Earth gravity but without air resistance. The initial velocity of the ball is V_o at an angle

\theta

to the horizon. The vertical dashed lines represent equal time interval,

\Delta

t. Consider "up" as the positive direction. $The figure represents the parabolic trajectory of a ball going from a to e in Earth gravity but without air resistance.
