// WHAT YOU WILL LEARN

26.8 m/s / 0.81 s = 33 m/s^2 = about 3.4 g, nearly 3x what tyres alone can grip.

// LESSON NOTES

QUIZ: 0–60 mph in 0.81 seconds. How many g is that? 🏎️💨
A) 1 g B) 2 g C) 3.4 g D) 10 g

Answer: C, 3.4 g!
60 mph = 26.8 metres a second. Reach it in 0.81 s → about 33 m/s² of acceleration. Divide by 9.8 (one g) → 3.4 g.

Tyres alone can only grip about 1.2 g, so the car needs help: fans for more grip and thrusters for extra push. A fast supercar (0–60 in about 2.5 s) feels about 1.1 g — this is three times more!
(0.81 s is from Tesla's own live timer at the demo.)

Read the voiceover (transcript)
  1. How many g is this launch?
  2. Zero to sixty in point eight one seconds! One, two, three point four, or ten g?
  3. It's C, three point four g! Sixty miles an hour is twenty-seven metres a second.
  4. Tyres alone grip about one point two g. So it needs the fans and the thrusters!
  5. Three times a supercar!
  6. Next: the jump maths! Comment and follow!
