I can't maintain a consistent study routine, if im productive for 5 days, I will then spend the next 5 days being unproductive its an annoying cycle that i can't seem to break for some reason, and don't get me started on my sleep schedule...

What's pissing me off even more is I could do this before, I studied consistently everyday for months and had a good sleep schedule when i was preparing for my SAT and the exams I'm preparing for now are even more important than my SAT so i don't understand why I can't lock in now.

I keep trying and failing, trying and failing again and again. Giving up is never an option in my mind, but man I don't wanna try again knowing I'm invetiable gonna fail and be back to where I am now. I'm just tired of being dissapointed with myself, I need to be better.

The only good thing about my current situation is instead of procrastinating all the time, I'm now procrastinating half the time.

Hoping I can find someone here who can relate to me and can give some practical advice.

" Let's say we have 2 wires that are made of the same material and have the same area of cross section x1 and x2

x2>x1 in terms of length and therefore x2 is less stiff than x1. "

" Now let's say x2 and x1 are equal in length, but x1 has a greater area of cross section than x2 in this case x1 has a larger stiffness than x2 "

The examples above was used in a lecture I was watching, and I don't fully understand them so could someone please explain it for me in simple terms?

I know that the elastic limit is the point after if which force is applied, the material will deform plastically.

I know the limit of proportionality is the point where the material stops obeying hooke's law

But I'm having a hard time wrapping my head around the yield point the definition given by my book is " the point at which the material starts to stretch without an increase in stress " , but that doesn't make a lot of sense to me and I'm having trouble visualising that in my head.

The word proportional is coming up a lot in my physics's lecture and I'm not sure that I fully understand what it means, does it mean that as one variable changes in value the other variable is affected as well?

The definition given by my book is " a single point through which all the weight of an object can be said to act ", but that doesn't make a lot of sense to me as if we took a human body for example all of our weight doesn't act at a single point, It makes sense for me to believe that its equally distributed throughout our various body parts.

It was a sidemen main channel video and in one portion of the video they were 2-3 contestants who were professionals atheletes and they were playing high jump and after each round the bar was going higher and higher and I think the boys were split into teams and backed one of the contestants to outjump the other. That's all I can remember, and i only remember this part of the video because i remember it being fucking hilarious and the boys had great reactions to how high some of the contestants could jump.

Any help is much appreciated i really wanna watch this again. 🙏

I know that when a skydiver falls out of a plane he/she will eventually reach terminal velocity but does the same apply for vehicles/machines?

My dad is paranoid about calling a taxi using an app because he thinks they're full of hidden fees. Does anyone mind sharing their experience with them and i see a lot of advertisements saying how its like 50% for your first few rides is this true?

1. Let's say I'm walking and the wind is pushing me forward from behind, in this scenario is there still air resistance acting in front of me? I guess what I'm wondering is if air resistance is limited to a single direction.

2. Let's say it's a windy day; would I face less air resistance if I'm surrounded by buildings than if I'm in an open field?

3. Why do i feel a gust of wind when a car flies past me at high speeds?
