# Acceleration: `Audi R8 Spyder: 7.72 m/sec²`

Acceleration is the derivative of velocity, and the 2nd derivative of distance. Use this calculator to calculate speed after a certain time of constant acceleration. E.g. after 5 seconds of falling (1g), the velocity is +- 50m/s.

### Acceleration conversion

 = `7.72` m/sec² = `8.443` yard/sec² = `772` Gal (Galileo) = `0.78722` g (earth gravity)

### Acceleration x time = speed

• After `3.6` seconds at this acceleration, the speed is 100km/h, the distance is 50 meter
• After `3.47` seconds at this acceleration, the speed is 60mph
• After `1` seconds (1 sec) at this acceleration, the speed is 7.72 m/s (27.79 km/h)
• After `5` seconds at this acceleration, the speed is 38.6 m/s (138.96 km/h)
