如何计算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.

分步指南

1. 1Horizontal: x = v₀ × cos(θ) × t (constant velocity)
2. 2Vertical: y = v₀ × sin(θ) × t − ½ × g × t²
3. 3Max height: H = (v₀ × sin(θ))² / (2g)
4. 4Range (flat ground): R = v₀² × sin(2θ) / g · max at θ=45°
