it took you like 10 seconds to explain why does the trolley have potential energy meanwhile my physics teacher couldnt through the whole semester. You're amazing

[yonatananteneh]

Bro I have a physics test tomorrow, through out my education I have been listening to u I got the highest result of my class for the whole year believe it and I want to tell u how much I appreciate it keep it up.

[e]

have a phys test tommorrow on a unit i completely blanked out on, your vids are short and easy to comprehend, a lifesaver!! :D, ty

[valalkobel]

i have 9physics assignments to finish in 20 hours and this is saving me from a breakdown

It's funny how most comment sections for youtube videos die out as the video ages but that doesn't happen with these videos becuse they keep there relevance as there are always new students coming to learn the same stuff

[williamshiflet]

This is epic. I have a midterm tonight and this is exactly what I needed.

[heyyy]

I have like 20.mins b4 my physics unit teat, ur saving me rn

[dhaneperalta]

This is really helping!! Thank you so much!

[peterandrews]

I like your explanations. thank you bro. keep making more videos.

I think everyone will understand better if you use this eq for the last problem : m g Hc +1/2 m Vc^2 = m g Hd + 1/2 m Vd^2. You thought me so well. Thank you so much

I love when he said "the kinetic energy is very low. Let me make sure that's right. And yeah that's it."

[lilysseize]

Thank you so much, hope this help me pass my final

[jonathan-wwsx]

Thanks a lot, I’m taking AP Physics 1 and this is what I need.

[ColtonReily]

I love this person and their explanation of physics!

[estrolex]

I can't remember how many times you saved me, you are a legend, I want to meet you in real life for real

Dude you magician, the day before my conservation test?

In the first question it states that the box slides down 150m inclined plane. I noticed when you went to plug in your number for height you used the 150m; would you not use 150m as the hypotenuse in order to solve for the height?

I just subscribed to your patreon and I can find the full video of this

I have a request. While adding new videos, please do that in context of an existing (or, if necessary, newly created) playlist. It becomes difficult to keep track of randomly uploaded Videos which respectively fall into several random categories (unless sorted) and searching them manually to discover which video is on what topic is not efficient. Feedbacks appreciated. Thanks.

Just wanna double check my understanding, but is the work done by friction equivalent to heat/thermal energy? Since heat energy is energy lost from the total mechanical energy?
