My physics teacher recommended this awesome channel.

Amazing editing, quality teaching, and very well done lecturing. Isn't a tad bit boring! Thank you for being a lifesaver in these troubling times!

[zakikhandaker]

I love these videos. it is educational and fun at the same time.

[alexandroochoa]

You are an excellent physics teacher! Thank you so much for all your hard work producing these videos!

[md.rahat-ul-ashekin]

Mr P, I just love you and your family. I am amazed by sensing your enthusiasm in Physics.

[AliRaza-szfp]

Very nice lecturing...♥♥♥ from Pakistan.

I prefer every Physics videos to be like this demonstrative. So wonderful and detailed.

1:27 Billy redeems himself after blurting out an answer without raising his hand. Respect!!

[josephinealtman]

I am actually enjoying learning physics! I never thought this day would come!!!!

Thank you, Mr. P.
You explained so well. I thought I was misunderstanding many mechanics concepts and your videos have helped me give strong foundation. Thank you very much!!!!

Can you make a railgun with that thing at 1:39 (hanging mass pulley thingy)?

[yogaraj]

Thank you sir.
Iam going to download all of your videos

[ZantherStone]

Question: So too much mass won't cause object not to accelerate but it will decrease it (like in the block experiment you did). Did the magnitude change happen due to friction? If table was frictionless would the slower and faster speeds still occur when you mass to the hanging thing or to the block?

[kanzulemaan]

Your videos are just great👌👍😊... Lots of love from Pakistan 🇵🇰💚

[bortoqal]

can you please explain catching up kinematics questions

[lokeshjoshi]

Please make for psedu force you are the best

[mohfares]

though my native language is not English but I understood your explanation
thank you from Iraq 💜

[noimspartacus]

Reminds me a little of Miniminuteman. Also, a smidgen of David Benetes. Anybody else?

[norahh]

not me watching the entire dynamics playlist on 2x speed in preparation for a test tomorrow

[greedskith]

When you fell.. can I just say you where enjoying the moment 🤣🤣
