# PROJECTILE MOTION (HORIZONTAL TRAJECTORY) CALCULATOR

Projectile motion calculator calculates the initial and final velocity, initial and final height, maximum height, horizontal distance, flight duration, time to reach maximum height, and launch and landing angle parameters of projectile motion in physics. Moreover, following plots are drawn for the projectile motion.

- Height (or Vertical Position) vs. Time

- Vertical Velocity vs. Time

- Horizontal Position vs. Height (or Vertical Position)

- Horizontal Velocity vs. Time

- Horizontal Position vs. Angle

The effect of air resistance is ignored in calculations. Projectile motion formulas used for calculations are given in the "List of Equations" section.
