u (launch) u cosθ u sinθ Peak H = $u^{2}$s$in^{2}$θ/2g H R = $u^{2}$sin2θ/g θ

Components:

• Orange dashed arc: parabolic trajectory
• u cosθ (green, horizontal): constant throughout flight
• u sinθ (green, vertical): reduces to 0 at peak, then reverses
• H: maximum height = $\frac{u^2\sin^2\theta}{2g}$
• R: range = $\frac{u^2\sin 2\theta}{g}$, measured along ground
