Does OnPhysics still reply to comments

please make all the videos for SPH4U, ur channel is the reason i understand all these concepts and do good on my tests thank you so much for everything you do

thank you so much for uploading these vids, i have my physics exam tmrw and could not have possibly understood these concepts without ur videos, thank you so so so so so much again

THANK YOU. You don't know how much this helped

15:10 but if you add 5 more meters, the velocity and Eg change, thus doubling the amount of energy. So why id you say the energy remains the same?

Particles move up when the wave passes the return to the equilibrium, net motion is zero, all that’s transferring is energy by the wave, no motion or force is happening, it’s just the energy/wave that’s moving but the medium itself isn’t

8:12 b/c Fn is zero. 🙂

4:33 say that again...

4:33 say that again...

4:33 those who know 💀

I would like to thank you for giving me an 85% on my energy unit (I made goofy mistakes that I will not make on the exam)

I would like to thank you for giving me a 97.5% on my forces unit

Thanks man 👌

When the light changes its medium, why are we calling it phase change instead of refraction?

bro is carrying my whole class

will he respond

You have saved me a truly infinite amount of problems you are the best thank you so much

real

Hey there, I know this video's quite old. But I think that the last question should be 6.25kg? My final equation was: m1 = m2/(sin (theta) + 0.25cos theta). My static friction is acting in the opposite direction, by the way.

me: *likes the video before watching it because Mr. OnPhysics never misses* 😌

At 13:17, shouldn't it be Fnet = +Ft -Fg since Ft is positive (pointing upward) and Fg is negative (pointing doward)?

"hockey, cool" (5:57) is such a canadian reaction. Thank you so much for the videos! They are so helpful to this day!!!

Thank you so much! Lesson 1 - Completed! 59 more to go!

for last equestion, why do we need to find diameter? why can't radius - radius work? 0.14 - 0.12

For last question, why did 150 n/c, the electric field becomes negative? -150 in the equation.

HERO!!!!!

Balistreri Tunnel

8:03 you calculated 30sin25 instead of 30cos25 here

Could you please send the answer of last b and c questions?

I can’t thank you enough, I didn’t do well in grade 11 physics and I failed to get the help I needed…I binged this all summer so I could prepare for grade 12, now I’m pretty confident!

Thank you for the amazing video, Are you using the Nelson textbook or McGraw textbook?

Don't forget to Like.

great

Thanks for these vids ☺️

Most clear and to the point notes, no dilly dallying - all precise and everything one needs to know about this physics course, also able to download all source material which is great!

For the last pic for Motor principle, isnt the magnetic field line going to wrap the wire clockwise if looked from above?

since g=a_c for object orbiting a mass, does that mean that for every increase in the distance (radius) between them, the velocity has to be doubled to keep the object in orbit?

In the what is the missing forces question why dont we add F1 + 15N, than subtract from the 28N? Why did you subtract all those values?

I am previewing this course, thank you for posting theses videos

For the tugboat question, when calculating a, shouldn't the mass of the tugboat first be converted to g?

thanks a bunch 🖤

this is a gift from god

Where do we find the homework questions?

In which textbook can I find the homework?

Why do you use the same value as mu s in part a for calculating the maximum magnitude of static friction..

where can we find the homework?

i had an eureka!!! moment after watching this video

Guys for anyone asking how delta t was found in 13:00 here is something you need to know: According to the zero product property, if the product of two factors equals zero, then at least one of the factors must be zero. So the first t = 0 and the second t in the equation can be found by saying that the whole equation is =0 then calculate t.
