Oblique Projectile Motion

For launch speed u at angle θ, choose upward as positive. Horizontal acceleration is zero and vertical acceleration is -g.

x = u cos θ · ty = u sin θ · t - ½gt²v_x = u cos θv_y = u sin θ - gt

Time of Flight, Maximum Height and Range

Time of Flight

At landing y = 0. So T = 2u sin θ / g.

T = (2u sin θ)/g

Maximum Height

At top v_y = 0. Use v_y² = u_y² - 2gH.

H = u² sin²θ / 2g

Horizontal Range

R = horizontal speed × time of flight.

R = u² sin 2θ / g

Range and Complementary Angles

For same initial speed u, horizontal range is R = u² sin 2θ / g. Range is maximum when sin 2θ = 1, so 2θ = 90° and θ = 45°.

Maximum range: sin 2θ has maximum value 1. Therefore R_max = u²/g at θ = 45°.

Complementary angles: θ and 90° - θ give the same range because sin 2θ = sin[2(90° - θ)]. Therefore R_θ = R_90-θ. Example: 30° and 60° have the same range.

30° same range45° maximum range60° same range

Trajectory Equation

For standard projectile, use Elementor-safe equations and eliminate time step by step.

x = u cos θ · t, so t = x/(u cos θ).

y = u sin θ · t - ½gt².

Substitute t: y = u sin θ · x/(u cos θ) - ½g[x/(u cos θ)]².

y = x tan θ - gx² / (2u² cos²θ)

The equation has x², so the trajectory is a parabola.

Horizontal Projectile and Projectile from Building

Horizontal Projection

x = uty = ½gt²y = gx²/(2u²)

Upward Angle from Height

x = u cos θ · ty = u sin θ · t - ½gt²

Downward Angle from Height

x = u cos θ · ty = -u sin θ · t - ½gt²

Sign convention must be stated before using formulas. If downward is chosen positive, signs change consistently.

Very Important Advanced Projectile Results

Two times at height h: h = u sin θ · t - ½gt². Rearranged: ½gt² - u sin θ · t + h = 0.

For roots t₁ and t₂: t₁ + t₂ = 2u sin θ / g and t₁t₂ = 2h/g.

α-β theorem: For point P(x,y), join P to launch and landing points. From trajectory and range relation, tan θ = tan α + tan β.

Radius of curvature: At projection, ρ = u² / (g cos θ). At highest point, ρ = u² cos²θ / g.

Relative projectile motion: For two projectiles, perpendicular velocity condition is v₁ · v₂ = 0.
