# Acceleration calculator

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

 = `9.807` m/sec² = `10.72` yard/sec² = `980.7` Gal (Galileo) = `1` g (earth gravity)

### Acceleration x time = speed

• After `2.83` seconds at this acceleration, the speed is 100km/h, the distance is 39.3 meter
• After `2.73` seconds at this acceleration, the speed is 60mph
• After `1` seconds (1 sec) at this acceleration, the speed is 9.81 m/s (35.3 km/h)
• After `5` seconds at this acceleration, the speed is 49.03 m/s (176.52 km/h)
• ### Compare
