Calculadora de Aceleração por Vela Solar — Formula
## Solar Sail Acceleration
A perfectly reflecting solar sail receives momentum from reflected sunlight.
### Formula
**a = 2S * A / (c * m * d squared)**
- *S* = 1361 W/m2 (solar constant at 1 AU)
- *A* = sail area
- *c* = speed of light (2.998 x 10^8 m/s)
- *m* = total mass
- *d* = distance from the Sun in AU
The factor of 2 accounts for perfect reflection (momentum change = 2p).

Exemplo Resolvido
10 000 m2 sail, 100 kg spacecraft, at 1 AU.
- a = 2 * 1361 * 10000 / (2.998e8 * 100 * 1)
- a = 27 220 000 / 2.998e10
- a = 9.08e-4 m/s2
- About 92.6 micro-g
