How to use this calculator
- Enter the initial and final velocity and the time.
- Read the acceleration and g-force.
How it works
Acceleration = (final velocity − initial velocity) ÷ time.
Worked example
0 → 27 m/s in 9 s. = 3 m/s² (about 0.31 g).
Common mistakes
- Mixing km/h with m/s — convert speeds to m/s first.
- Forgetting deceleration is just negative acceleration.
Frequently asked questions
What does the g-force mean?
It compares the acceleration to gravity (9.81 m/s²) — 1 g is the pull you feel standing still.
