Launch settings

Speed (u) — m/s

Angle ° (−90 to 90)

Launch height — m

Gravity g — m/s²

💡 Tips
Angle 90° = straight up
Angle 0° = flat / sideways drop
Angle −90° = straight down
Try same throw on 🌍 vs 🌕 to feel the gravity difference!

🎯

The Scene Scales

Throw 5 m — see people & bushes. Throw 5 km — mountains appear. The world zooms to always show the full path.

🟠

The Orange Arrow

The arrow on the ball shows velocity direction. Watch it flip at the peak — that's where vy = 0!

🌍🔴🌕🪐

Compare Planets

Same throw on Earth vs Moon — the ball goes much further under lower gravity!

Drag the time slider to freeze and inspect exactly where the ball is at any second of flight.

Equations used

v = u + g × t

s = u×t + ½ × g × t²

v² = u² + 2 × g × s
