Force measurement from accelorometer in Soccer ball

AI Thread Summary
To calculate the impact force of a soccer ball using a 3-axis accelerometer, the frequency of oscillations is not directly proportional to the force, as it is influenced by the mass of the accelerometer and the elasticity of the rubber bands. Instead, the amplitudes of the oscillations, particularly the first amplitude, may provide valuable data for force calculation. Calibration of the device is essential to ensure accurate measurements. Understanding the relationship between oscillation characteristics and force will be crucial for effective analysis. Accurate force measurement can enhance insights into the dynamics of soccer ball impacts.

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.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
