What it practises
- Concepts & theory: The science and maths behind the game: reflection, orbits, waves, circuits, ciphers.
- Spatial & visual perception: Judging angles, rotations, paths and positions in 2D and 3D space.
Playing rarely teaches the idea behind the game on its own, so every concept game comes with a brief and a check question.
Quick lesson: Projectile motion
Without air resistance, a shell keeps its sideways speed while gravity pulls it down at a steady rate. The result is a curved path called a parabola.
Check question
On flat ground with no air resistance, which launch angle gives the longest range?
- 15°
- 30°
- 45°
- 75°
Answer: 45°. 45° balances time in the air against sideways speed, giving the maximum range.
