Thank You sooo much!!! I can't tell you how confused I was with Physics. My teacher isn't the greatest so needless to say I always dread going to class. I'm a huge proponent of Youtube for supplementary education. Having said that I've had to weed through videos at times to find the best one. Your teaching style works for me and I greatly appreciate your services. Thanks for saving me!!!

The best way to learn physics is your videos ❤️️❤️️👍🏻 THANK You

[suhailpanjwani]

Thank you for sharing your knowledge. bless you.

These videos are so much help thank you!

Finally. An explanation for what to do when the object isn't just being dropped. Thanks.

[yuriezelshin]

Thumbs up! Exam 2morrow, i hope this can help me :)
I put all of my hopes in ur lessons :)

[Zyiiodlait]

I can't express how much simpler your approach to Physics is compared to my professor's. Thank you!

@Step-by-Step Science, sir I couldn't understand what you did at 5:13 in deriving the formula for time. could you explain it a little more? I got lost right there and couldnt continue watching your next videos bout this free fall :(

[faizasikandar]

Also tell about formulas in projectile motion

[sevenoctobers]

Why can't my Physics teachers teach like this??

[Ceddy-dd]

Why is there 2 final velocity and how will u know if u need to have two Vf?? Thank You po😂

[thut]

You just have no idea how much I hated physics before watching your demonstration videos! You're a hero.

Hi Brian!
I have to congratulate you. These are the best videos I've watched on Youtube👍Thank you so much and Keep it up.

Dude fucking thank you, i was wanting to rip my hair out till I was bald doing this. I kept getting wrong answers everytime and did trial and error for like 15 minutes per problem and it was just so frustrating. Thanks for showing it and having a great explanation.

[Electromagic]

i love how you show everything in order and explain in order too, excellent, thanks very much

[RaivoltG]

Thank you very much for the refresher! I subscribed and look forward to seeing your videos!

[daynahazime]

Super useful - thank you for the great explanations and showing the variations of the calculations! :)

[mrmask]

Excuse me sir, isn't the acceleration of every free fall object is a= -9.8 m/s² Then why is yours a= -9.81 m/s²?

[danniellekarise]

Excellent explanation! I’m so glad you posted these videos. 👏🏾

[promisedroses]

The part 1 is freaking amazing, so easy to understand!
