Force measurement from accelorometer in Soccer ball

[Nathaniel01]

I have a 3-axis accelerometer suspended on rubber bands inside a soccer ball and am wondering how to calculate the impact force of the ball with it. I have an intuition that the force will be proportional to the frequency of the oscillations of the sensor after a collision but I am having difficulty figuring out anything more specific.

Thanks for any help in advance.

No. The frequency is determined solely by the mass of the accelerometer and the elasticity of the rubber bands.

Ok, any idea how to calculate the force then? Thanks

The amplitudes of the oscillations may give something useful, especially the first amplitude. You need to calibrate your device, though.
