I have seen too many philosophers building theories that just - well - didn't match reality. It is always good to work interdisciplinary and I think it is crucial for a philosopher to know what those science people seem to "know" about everything out there.
this gives you (meters per second) per second.īy the way, you can apply exactly the same ideas I mentioned before (secant, tangent, derivative) to the velocity graph and you will see that acceleration is the derivative of speed.īy the way, I would really encourage you to keep reading and thinking about physics, mathematics and the other sciences. Now just look at the units: On the right side, you already have meters per second for speed, and now you are looking at the change of this speed over time. How do you calculate average speed? So, if the apple would have been travelling at the same speed all the time, how big would this speed need to be?īasically, the formula is $v_$. Now, let's have a look at the speed (and now, again for sake of simplicity, assume the object is travelling in a straigt line, otherwise you'll get some more general vector spaces that might be nasty to imagine). You can speak of distance as a function over time (that means, you can plot it with the x axis being the time axis and the distance at a given time are the y values). What is happening? The position of the object changes over time, so here we've got a connection of two fundamental physical units, distance and time. Let's take some object - without restriction and for the sake of simplicity, let's assume it's an apple - and push it around (in your head). It is some sort of thought experiment that is quite useful in that it helps describing our world. This speed and acceleration stuff isn't real. Let's get clear about something important (but rather philosophical) first. I am assuming you have heard of derivatives if my assumption is false, I am sorry for that, but in this case this answer might not be helpful to you. Maybe it will be even clearer to you if one explained it in a more fundamental way, but for this, we need a little bit of senior grade mathematics.
