How to remember physics derivation easier?

hmm let's see

Explanation:

ok, ill use the second equation of motion, u see its quite simple

recall that

average velocity= u+v/2

now think of that v like a box you can can call it velocity lol obviously its velocity

now remember the first equation of motion which is

v=u+at now this is inside the box, now you have to replace the v with it

then it becomes u+u+at/2

now u notice there are two initial velocity u know what to do with that

now it becomes

2u + at/2 now since the numerator applies to both then you can simplify it like this

2u/2+at/2

all the same the pont im trying to make is that you can use imaginative ways to mater derivation you can also reverse it if you don't unferstand you can drop your number

this is poiselle's equation from fluid mechanic in physics. mech eng
