Thanks, I actually thought the photos were pretty unorganized and thought that writing what I was doing, on the thread, would give more order, glad to see it doesn't, also, I completely forgot I had to consider the Energy of the friction force of the air, so thank you very much for the reply
The Problem
So, I know the basic, the basic differential equation of movement in terms of the angle it is formed, which has the form: 0 = g⋅sin[α(t)] + α''(t)⋅l. However, I decided to consider the friction force of the air, which is always contrary to the movement, and proportional to the...
So... by the title I most say thay if I were to read this I'd think "This kid got lost", and I thought so too, but recently I've been having a lot of interest relating to simple science, but with a different focus (for example, parabolical movement, but applied with friction force, and how to...
