Please sir, can you explain the second average speed formula. The first one was Xf - Xo/t which made sense but this second one: S = Xf + Xo/2 is really confusing sir.
Can you please link me a video or the video I tried to go ahead on this problem and failed horribly I just need more examples and example problems with solutions so i can maybe work through them on my own to understand it better because I’m horrible at kinematics and I’ve already made it to 2d motion please
Thank you. I am an online college student and I always come to your channel when I'm struggling with subjects. You always make them so much easier to understand and the way you break things down so simply really helps me feel confident with the material.
Hi Christiana! If you need even more practice, we have made a playlist of hundreds of worked out problems for students like you who want more practice problems! A lot of viewers that use our channel are also studying for the MCAT! Here is the link: ua-cam.com/play/PL_3h4GvKc6GAniH6iyxOqX35ZI-tGEChJ.html Cheers and good luck with studying! 😀
For self-reference... Scalars are just the items themselves (magnitude) with no direction or anything (speed, distance) and Vectors are the items with the direction (velocity, displacement). Velocity is the speed with the direction and is calculated with Displacement/Time while Speed is just the rate at which something moves (no attention to direction, hence why it is not a vector) and is calculated with Distance/Time. Scalars like speed and distance have no direction, so they are always positive, and vectors like velocity and displacement do have directions, so they can be positive and negative. You calculate distance by adding up the amounts traveled as their absolute value, regardless of direction. You calculate displacement by comparing the final position with the initial position (no attention to distance but instead to final distance from initial distance) (ex. Sal moves 10 in east, 11 west: The displacement would be -1 because the initial position is assumed to be 0 and after Sal went 10 places east, he returned 11 west, and so ended up 1 place more west than where he started, which was 0, hence since it was going to the left side, the displacement is -1. Instantaneous (speed) vs average (speed) is that instantaneous is calculated as an absolute value and tells you the speed at an instant in time, while the average speed tells the average over an interval. Avg. velocity is displacement (final position minus initial position)/time, while Inst. velocity is the change in displacement (final position minus initial position)/over the change in time. Displacement along the x-axis and y-axis are essentially the same, the only difference is that it is the final position minus initial position in the x and y axis accordingly. Average velocity is (displacement) change in position (X final- X initial; displacement;)/time, while average acceleration is the change in velocity (v final- v initial)/time.
mannn u saved my maths in high school now my chemistry & physics in college, couldnt thank u enough, n none of my teachers do teaching n explaining better than u do
Really missed the time when i was learning physics in foundation study. Im currently in first year mechanical engineering study. I really like all your videos. It really help me during my foundation study.
As always thank you, every subject that I struggle with I come to this channel and feel like i'm getting tutored one by one because you actually explain the reasoning behind the math, not just the plain equations that are given just to memorize!

Trying to review for my Physics midterm and I learned this stuff months ago so I'm watching this to refresh my memory of the knowledge, thank you man! 💪‼️
Thanks! 😢 I have been cramming all day because tomorrow is our exam and watching this video was my lifesaver especially I have trouble remembering things
This guy know how to explain clearly every each of problems. He don't miss any problem what I confuse. Really useful for us because his explanation is totally understand for all.
Thank you so much for these videos, i love physics but my mechanics teacher isn't really the best at explaining these concepts, through your vids i genuinely learn so much!!
I have a question. 8:04 to calcululate the initial postion I would assume it would be 0 right? And then the final postion I would do 13-4 =9 and then using the formula 9-0=9 . Is this the correct way? Please help me I’m a 9th grader and a little scared about physics 😢
Anyone noticed the inconsistency, or is it just me??? In the beginning of the video -4-(+13) =+9 and here at the end -90-(+50) =-140 This is confusing when I try to find Xfinal - Xinitial
Then why is the displacement in the first example -50 instead of -250? If the particle started at the origin and traveled 100m east, then turned back around and traveled 150 west. It should be final-initial, which would be -150-100?
@@tinewordsmith126 the last example is different. It’s saying that in 5 hours you go from somewhere to the east to somewhere in the west. Final-initial for displacement gets us -90-50=-140
i hope you don't mind me asking do you think i can teach myself ap physics 1 through youtube videos and khan academy? where i live, ap isn't a thing but i wanna try so yeah
i used to watch this channel before every test, now a year later i am an art student in college, and the moment i heard this guy's voice i had some real ptsd flashbacks lmaooooo
