In force-spectroscopy an important value is the loading rate [pN/s]. Is there any more propagated term to explain the force derivative with respect to time to the public? For example, the time derivative of acceleration would be "jerk".
Loading rate is important, but for public is more accessible the Loading speed(µm/s). Depending on what phenomenon you want to explain or emphasize on, maybe Loading Speed might hint a clue. If you could be more specific about what do you need to explain to public, maybe it would ease to get suggestions.
Thank you for the reply! The loading rate is a convolution of loading speed and force-distance properties. Therefore loading speed is a good starting point to explain the loading rate. At the "long night of sciences" people from Berlin are visiting our labs. There we just plot the diagrams in force over speed, making things much easier (we also have a working large-scale model measuring magnets, equipped with a digital oscilloscope).
Thus we can explain the term, but it would be great to give a comparison to other phenomenons in daily life.
Hallo,
it would be nice to start by visually explaining the effect of the velocity rate to the force in the time scale, on some stuff taken from real-life, that could resemble the behavior of the proteins (or other material under study) under different loading rates. For example you can make two persons pull at different velocities a rope of some material (you need to find out what!) and the effect of that in terms of pN/s. From there you can more easily extrapolate the concept of loading rate. This is how I tried to visualize it, having a bio-background.
Usually, I just say: "loading rate = dF/dt" and show it on a force curve in format F(t).
The term "loading rate" is very old, it is from the mechanics of deformation. In my opinion, it is not necessary to make an ersatz for it. "The speed of the force change" is an intuitive clear explanation.
