At 3:55 you said "the velocity is not proportional to the distance traveled and then towards the end of the video you say that it is directly proportional to the distance. I am just a bit confused on that which of the two statements are true?
He's a terrible teacher, don't mind him. He also cancelled out the 1/2 on the left side of the equation without explaining why, lol. In algebra you don't just magically cancel out something on one side of the equation but not the other, lol. If that wasn't enough, he also cancelled mass on one side of the equation but didn't cancel mass on the other side but instead cancelled Force, lol. If force was, let's say, given by "mass" and "gravitational force" (just for example, not talking specifically about this video's problem) then you can cancel mass on both sides of the equation because they cancel eachother out but he cancels mass on one side and Force on the other. The teaching of algebra & physics in this video is extremely poor. I really hope this guy isn't an actual teacher because even if he can do the work correctly, he does a poor job at explaining things. If I just magically cancelled out a number on one side of an equation but not the other or did the same with a variable (eg. "x"), my teachers would be like what are you smoking? Lol.
@@vincer9960 he cancelled the 1/2 the mass and the force because they are all assumed to be constant. Notice how he didn’t say v^2 is equal to the distance travelled. He said directly proportional to. This means v^2 is equal to a constant (in this case 2F/m) times the distance.
That's what I thought. But that's fine as we are investigating the effect between initial velocity and stopping distance - and friction is what causes the stopping (or would run forever) so we don't want friction to be constant do we?
A Level Physics Online well can you start cuz that will help me alot I don't have a good physics teacher in school 😂😂😂 he didn't even give us the syllabus so I'm lost in physics
A Level Physics Online and the problem it's my favourite subject but I don't have a good teacher to teach us how to solve past papers keywords or anything even the notes are very bad😂😂😂😂😓
Congrats on 30k subscribers! keep up the amazing work!

I wonder how Kimi Raikkonen stumbled into a physics experiment... XDD
Great vid 👍
Hi there, I would like to purchase your A2 physics material for AQA. How can I do this as i have been waiting a while. Thanks.
Joe Bloor Sorry about the delay. Hope to have something up and running over the weekend.
A Level Physics Online That's great. Thanks. Your videos are extremely helpful by the way!
Friction is not a constant, it is velocity dependent.
That's what I thought. But that's fine as we are investigating the effect between initial velocity and stopping distance - and friction is what causes the stopping (or would run forever) so we don't want friction to be constant do we?
Do you do IGSCE videos?
