Cara Menghitung Projectile Motion
learn.whatIsHeading
Projectile motion describes the parabolic path of an object launched into the air and subject only to gravity (ignoring air resistance). Key equations relate launch speed, angle, maximum height, horizontal range, and time of flight.
Panduan Langkah demi Langkah
- 1Horizontal: x = v₀ × cos(θ) × t (constant velocity)
- 2Vertical: y = v₀ × sin(θ) × t − ½ × g × t²
- 3Max height: H = (v₀ × sin(θ))² / (2g)
- 4Range (flat ground): R = v₀² × sin(2θ) / g · max at θ=45°

Launch 20 m/s at 30°
Hasil
Range: 35.3m · Max height: 5.1m · Flight time: 2.04s
20²×sin60°/9.81=35.3m
