Thread: Eclipse and Accelleration of the Earth ?

So soon the moon moves between the Sun and the Earth, by eclipse, - and the 3 objects will be aligned, - how fast can the Earth possible accelerate due to that ?
And how can it be calculated ?

You can calculate the motion of the moon and earth by considering the earth and moon as orbiting a common barycenter, and that system is orbiting the sun. Newton's laws of motion are good enough for most purposes.
