It is the 3rd picture which contains the sentence that is causing me grief.
It says 'Since the velocity is changing uniformly we know that this average velocity must be given by:
average velocity = (v+u)2.
Without using the other equations of uniform motion, why is this the case, why must it...
Yes that makes sense, thanks.
However in the book, it seems like it is saying that through a common sense approach this can be explained; i.e. not through using the other formulae.
Here is how it is written in the book:
Hi,
I am reading through a study guide and currently going through the kinematics section.
In the section on uniform acceleration it gives all the standard formulae and explains how they are derived.
It says that average velocity = s/t, but also that it is equal to (v+u)/2 if the...
