Acceleration calculator
Acceleration is the rate of change of velocity, and the distance follows from the kinematic equations.

Acceleration
5.556m/s2
- In g Multiples of standard gravity, 9.80665 m/s2 exactly.
- 0.566 554
- Distance covered
- 69.45
- Distance if it had started from rest
- 69.45
Show the working
- Initial speed = 0
- Final speed = 27.78
- Time taken = 5
- Acceleration = (27.78 - 0) / 5 = 5.556
- In g = 5.556 / g0 = 0.566 554
- Distance covered = (0 + 27.78) / 2 * 5 = 69.45
- Distance if it had started from rest = 5.556 != 0 ? 27.78^2 / (2*5.556) : 0 = 69.45
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- a = (v - u) / t
- distance = (u + v) t / 2
- v^2 = u^2 + 2 a s
Standard gravity is exactly 9.806 65 m/s2 by definition, so the g-force figure is reported as exact.
