Physics is the most fundamental science which explains the universe. No small task, right? Sometimes it seems a little daunting, but I think you can do it! And I'm pleased to offer a little companionship along the way.
This channel contains 29 Modules covering the physics you'll see in high school AP Physics or introductory physics in college. First Semester Mechanics: Modules 1-15.
Second Semester E&M: Modules 16-29.
Thank you to all my Fandersons (TM) out there! For you, I am revamping this channel to include all my squeak-free videos in a much more organized format. (I know, those squeaks were brutal.) Hopefully you'll enjoy it.
There is also a donate link above, which will go to my kids' college fund and various charities. It's totally voluntary, but much appreciated.
Cheers,
Dr. A

Falling Box with Pulley | Physics with Professor Matt Anderson | M12-23
A box is tied to a rope coiled around a pulley. The box is dropped and the rope begins to unspool. As the rope starts to rotate the pulley, what is the downward acceleration of the block? You might reason that it has to be less than g, but by how much? Let's work it out.

Relativistic Momentum | Physics with Professor Matt Anderson | M29-06
Переглядів 8 тис.2 роки тому
If you want to double the momentum of a particle by increasing its speed, what do you need to do? Well, you might say double the velocity. In classical physics (for low speeds), you would be right. But once we get to very high velocities, we know that relativity kicks in and things get a bit weird. So maybe it's not just doubling the velocity anymore? Let's sort this out.

Let's look at a specific example of single slit interference. In this case, we have a known slit size, and when we shine light through it, we get a diffraction pattern. If we measure the angle from the central maximum to the first minimum, can we calculate the wavelength of light based on this. How do we do it? Physics with Professor Matt Anderson

Amazing
Love your videos
Professor, light after two bounces returns parallel. In a cube it bounces thrice . Can you please clarify how three bounces gives parallel instead of two bounces as you explained here.
Love it 😍😍 amazing!!😘💖
Why this equation 1/2mv^2 = 1/2 K x^2 turn into this v^2= k/m . X^2
Pressure requires a container, especially if it stops at any point without mixing becoming more evident as time goes on THEN you relearn most of what this guy has taught you
Very helpful!
Such a wonderful revision of school time. Very nicely explained .
all I can think ab is whether he's writing backwards or if the camera is flipped but if the camera was flipped then his class wouldn't be able to see the words so... he's writing backwards......????
Clearest explanation I have seen yet!
he is underrated ngl
thx, very helpful
How do we determine the amount magnetic field lines in an area. I know we used the example 3 here, but how would you determine how much they are really
Why not we never tried to convert this pressure to energy?
sir, i really love your explanation (love from india)😄
thanks sir
Is it possible to go inside the center of earth as there is no gravitational acceleration?
Wrong! The water level goes down! Your theoretical ice doesn't work because you have too much ice out of the water, that's not how it works in real life, there is always more ice under the water, than above. So your "pen, paper" math you have going on here has no real world mechanics working, FALSE INFORMATION just because your math says so doesn't mean it's fact.... I wonder how much this has happened for so many other things that we think of as "fact"....
Prof, we can use the kinematics equation when its un-uniform motion? No right? I mean the a isnt constant. So why you said we can get the at from kinematics equations?
sir, i"ve really love the way you explain and more over i can really understand it😄
Thank you sir, you made the topic easy to me😁😆
Thanks for another awesome video! Love from Bharat
I wonder where that fucking sound is coming from in the background.
a ver, lo voy a simplificar i=x2+y0 \ o=x1+y1, hacen mucho quilombo al pedo, usen equivalencias es mas simple
Anyone else blown away about how he's writing backwards so legibly?
I can produce E = mc² using any physics. Newtonian derivation of E = mc² *In Newton’s law:* Force = mass x acceleration (Areal velocity = constant is included in Newton’s law) Newton’s gravity law F = - (G m M /r2) **r1** Acceleration in mathematical form is: (rʹʹ - r θʹ2) **r1** + (2 rʹ θʹ + r θʹʹ) **θ1** Force = mass x acceleration = m x [(rʹʹ - r θʹ2) **r1** + (2 rʹ θʹ + r θʹʹ) **θ1];** Force = F = mass x acceleration = - (G m M /r2) **r1** And m (rʹʹ - r θʹ2) = -G m M /r2 ---Newton’s gravitational force law. And (2 rʹ θʹ + r θʹʹ) = 0 -------------- Kepler’s constant areal velocity law. Divide Kepler’s law by r θʹ Visual distance: r = (distance) r₀ x e± i ω t Visual angular speed θʹ = (angular speed) θʹ ₀ x e± 2 i ω t = r₀ e± i ω t And θʹ = θʹ₀ e± 2 i ω t And (2 rʹ / r + θʹʹ/θʹ) = 0; rearrange: (2 rʹ/r) = - (θʹʹ/θʹ) = ± 2 i ω *In Kepler law*: Areal velocity = (r2θʹ) = constant Or (r2θʹ) = k; r = distance; θʹ = angular speed Take the derivative: d (r2θʹ)/ d t = 0 And (2 r rʹ θʹ + r2θʹʹ) = 0; divide by r2θʹ And (2 rʹ / r + θʹʹ/θʹ) = 0; rearrange (2 rʹ/r) = - (θʹʹ/θʹ) = ± 2 i ω And (rʹ/r) = ± i ω And d r/r = ± i ω d t And ∫ d r/r = ∫± i ω d t L n (r/r₀) = ± i ω t L n e = L n e± i ω t And r = r₀ e± i ω t And - (θʹʹ/θʹ) = ± 2 i ω And θʹʹ/θʹ = ± 2 i ω The solution is: θʹ = θʹ ₀ e± 2 i ω t If r₀ e i ω t; θʹ = θʹ₀ e- 2 i ω t If r₀ e - i ω t; θʹ = θʹ₀ e 2 i ω t E = mc² S = r ℮ ỉ ω t P = [v + ỉ ω r] ℮ ỉ ω t (P. P) = [v² - ω² r² + 2 ỉ ω r v] ℮ 2 ỉ ω t E = m (P. P)/2 = (m/2) [v² - ω² r² + 2 ỉ ω r v] ℮ 2 ỉ ω t E = (m/2) [c² - c² + 2 ỉ c²] ℮ 2 ỉ ω t With ω r = v = c E = (m/2) [2 ỉ c² ℮ 2 ỉ ω t] E = (m/2) │2 ỉ c² ││℮ 2 ỉ ω t│ E = (m/2) (2 c²) E = mc²
Wow I like it your expression methods God bless you
The rocket example everyone gives when explaining escape velocity is very misleading, since rockets are usually percieved as having their own means of acceleration, so they can escape the Earth at basically any speed as long as said acceleration is greater than or equal to 1g (assuming its moving directly away from the planet) . Escape velocity, however, is about initial speed of a body without any forces applied to it other than gravity, just like you said in the video
How does this work that he is writing on glass or is he really? Is he writing on a mirror?
He's writing on a glass board. In the setup he uses for filming, he inserts a mirror. A live student watching his class will see the board reversed, and will see a live video feed on a monitor on the side.
9 years before and still understandable. Greate Teaching sir 🗣️🔥
Climate change folks say the ocean rises because of melting ice. 🥴 but common sense and this math says that’s not the case.
11 years ago damn
Pr Ayache made made me watch this for the catch-up exam 🥲
Thank you for sharing these videos! They're easy to follow and are interesting.
Very useful information
in certain problems, we assume the normal force to be equal to the weight, like in friction problems,are we neglecting centripetal force here?
In case it is not clear, Solution(2), we use the theta= 30 and plug it into V_bR*costheta to find the vertical component/component crossing the river.
An awesome EE prof! Really appreciate it. Thank you.
Kinda nuts this college kids think about everything so mathematically. I haven’t finished the video but I’m pretty sure the answer is basically zero. If you are in the dead center of the earth you’d be so close to the core gravity would not be pulling you anywhere. You’d be essentially weightless. Maybe I’m wrong
initial velocity would be changed at the last part right ?
Full video please
Amazing❤2024
Call me crazy but I just binge watch his content for fun😭😭 They're so interesting
I dont even know why i searched up for this
Sir one doubt,,,how was electron loss in the electric field not a conductor 😊😊
its an impressive lecture but i have never understood why they compress all these stuff in one semester😭
Where did you get that writing board??????
WHAT THE FUCK IS THIS SHIT 🗣️🗣️🗣️🗣️‼️‼️‼️‼️‼️
sir I'm from India and I watch your lectures definitely helps me thanks
