WHAT YOU ARE SEEING

In the ideal model, horizontal velocity remains constant while gravity steadily changes vertical velocity. Combining them produces a parabola.

Drag acts opposite the projectile's velocity relative to the moving air. Greater air density, area or drag coefficient increases the force.

A 45° launch maximises range only when launch and landing heights match and there is no drag or wind. Real trajectories often favour a lower angle.

Horizontal positionx(t) = x₀ + v₀ cos(θ)t

Vertical positiony(t) = y₀ + v₀ sin(θ)t − ½gt²

Level-ground rangeR = v₀² sin(2θ) / g
