Memorizing vs. Understanding in Physics

- In physics many students discover that they need to learn to understand the material rather than memorize it. This video discusses and shows examples of the differences between the two.

This video hits close to my heart because I have had this conversation with students on so many different occasions. The difference between understanding a concept and memorizing how to solve a problem. #PhysicsED #flipclass
I am a massive culprit to this. Test Thursday... Feeling down... Starting to stray off and lose connection with the topic/syllabus due to falling behind. A-Levels are hard and I knew this... but memory has always been my friend and now I am having to abandon it somewhat. If only you could teach me... perhaps I'll have to dedicate all my time to your videos or something... I have major concerns right now dude... just wish me luck for the future.
If I were still teaching an academic subject--yes, even English--this would re-inspire me to look for ways the problem shows up in my classes, and ways to encourage students to rethink their approach. Good stuff!
I'm currently in a "Calculus Based Physics Class" except that I feel like I'm not learning any Calculus Physics -_-. This sucks because I really am fascinated by the Calculus, and am not afraid of advanced math.
I like your channel because unlike others, you are not afraid to explain it from the bottom up, to go from the simplest and stupidest of things, all the way up to the most complex of equations. For this, I can't thank you enough...
So glad to know you appreciate my work!
you are great inspiration to me.....you enjoy ur work that is awesome and the amount of time you spend on your lectures ...im amazed....great work ...keep going
Holy, I can't believe I just finished the Motion in Two Dimensions playlist! Considering that I didn't understand much of our introductory projectile motion course back in 9th grade, I felt quite scared entering this flipped classroom. Having finished the playlist, however, I must say that I learned so much watching these videos and solving problems here and in other external sources, and honestly, your visualizations and explanations are top-tier. Really.
Thank you so much, Mr. P. I've never felt this jovial and ecstatic studying introductory physics (ha, and I'm sure one day physics will get harder, oh well), to the point that frankly, I am more excited to watch your physics tutorials than I am to attend my classes. Now, onward!
I hope you continued onward!
Thank you for your videos! They have really helped me in my Ap Physics 1 class. Also I realize now that I do tend to memorize things and see the pattern instead of understanding it. But not any longer! Thank you again!
Wonderful!
As a Game programmer I find Vectors to be very self-explanatory :) Though I don't need to use complex equations most of the time to be perfectly honest , I have flops :) :) :)
Very interesting! thank you very much I will keep up the hard work until I will developpe a solid understanding of why/how. Math actually I don t really memorize but I can picture it easly! it same as pattern recognition* :) thanks again hugs
+ihonestytruthful Thanks for the hugs. :)
Sir you are great.

Thanks. From The United States.
+ a new subscriber ...Great video sir ....
Thank you!!
So how do you resolve components for something on a incline in circular motion?
When something is moving in circular motion, you need to sum the force in the in-direction and the direction perpendicular to the in-direction. When a car is moving on a banked curve (the most common example of inclined circular motion), the circle the car is moving in is in the horizontal plane so the in-direciton is in the horizontal direction, therefore you need to sum the forces in the in-direction and the y-direction.
In the free body diagram you have the force of gravity (straight down), the force normal (perpendicular to the incline and up) and the force of friction which is usually down the incline because the car is moving fast enough where without the force of friction the car would slide up the incline. [It is possible the force of friction could be up the incline because the car is moving so slowly that the force of friction is preventing the car from sliding down the incline.]
The force of gravity does not need too be resolved (or broken) into components because it is already in the y-direction. The force normal and the force of gravity need to be broken into components in the in-direction and the y-direction. You need to be careful to use the correct angles when breaking these into their components.
Hope that helps!
Your student stereotypes are hilarious!
I don't know what you are talking about. Billy, Bobby and Bo are _real_.
I've run into similar issues teaching electronics courses at a local community college. Some students are very good at memorizing solution methods for specific problems, but fail miserably when asked about a slightly different problem. Ultimately, I think understanding core concepts and teaching students how to approach (think about) problems is more important than short-term memorizing how to solve specific problems. Do you have any book recommendations on teaching methods/strategies that promote student understanding? My background is in Electrical Engineering, and I have only recently (within the last 2 years) taken up teaching.
I don't understand high school physics 😐🤨🤔😢
His Hair Is Like Nima Arkani-Hamed
"I thought High School Physics for 13 years" - bruh I thought u were a college grad student or somethin '-'
