🎯 Slingshot Material

Sling PE 0.0 J

Grav PE (mgh) 0.0 J

Kinetic KE 0.0 J

Total E 0.0 J

Set velocity & angle with sliders, then pull the band until it glows — PE stored = KE from your slider. Stiffer material = shorter pull for same energy!

Equations

x = v₀cosθ · t

y = v₀sinθ · t − ½gt²

vₓ = v₀cosθ

vy = v₀sinθ − gt

R = v₀²sin2θ / g

H = v₀²sin²θ / 2g

θ = fixed launch angle
φ = tan⁻¹(vy / vx) — changes with t
