Really nice job, just a detail, at 3:28
when you put t=(d/v) you wrote t=(m.h/m) if im correct it should be the other way around.
Nice work, and thanks for making these vids =)

Sorry, algebra trick
on top is distance (m)
on bottom is velocity (distance/time or m/h)
When you divide m by m/h you can factor m/m and m/1/h. And that is the same as mh...
So it ends up being mh/m. The distance cancels out and you are left with units of time. Thanks for the help.

arghhh, lol. your right. im sorry. i was looking at it only with my eyes, not with my brain -_-"
algebra pwned, lol. sorry again
keep up the good work =)
Yea... I have stood up in front of my class and done an entire derivation to prove how F=m/a only to realize that I was thinking about something else. (F =ma)..."Never mind".
3:58-4.39
d= (at^2)/(2)
Wouldn't t= +-sqrt (2d)/(a)
Wait, now that I think of it, it couldn't be a negative because the distance an object accelerates over time could not be a negative.

Algebraic manipulation is much easier for me now. Thanks!

Glad to help. I never got it when I was in school myself.

Explained very well!

Absolutely wonderfully explained. Wish my teacher explained the reasoning process like this!

I wasn't very good at this as a kid. Had to figure things out myself. People who are successful (like math teachers) don't understand.
