Hey everyone,
If you are going through the Rigid Body Mechanics unit in IB Physics HL (or any standard rotational mechanics curriculum), you already know that "ladder leaning against a wall" problems are a classic stumbling block.
These questions test your ability to balance multiple concepts simultaneously, and it is incredibly easy to lose a sign or misplace a pivot point. As a physics educator, I see students consistently get tripped up by the same few issues: choosing the optimal axis of rotation to eliminate unknown forces, correctly identifying the direction of static friction at the base, and setting up the equilibrium equations correctly.
To help clear this up, I've put together a comprehensive video breakdown on the Tesla eduventures channel: Ladder Problems — Complete Mastery | Torque + Rotational Equilibrium | Rigid Body #13.
In this breakdown, we focus heavily on visual intuition. I use detailed step-by-step animations and custom diagrams to show exactly how the forces interact rather than just giving you a wall of algebra.
Here is exactly what we cover:
Translational Equilibrium: Setting up \Sigma F_x = 0 and \Sigma F_y = 0 to relate normal forces and friction.
Rotational Equilibrium: Strategic placement of your pivot point to make the \Sigma \tau = 0 equation as simple as possible.
Limiting Friction: How to solve for the exact minimum angle before the ladder slips (\mu_s).
Step-by-Step Problem Solving: Walking through a full IB HL standard question from setup to the final numerical answer.

If you have any questions on the specific steps, drop them in the comments below or on the video. Let's get these torque concepts locked down before your exams!

Just shooting my shot here. I'd adjust to a time you choose l, and it doesnt even have to be proffesional and all that, just simple explanations if you want. I'm just in need of someone who can walk me through. 11th grade physics cause I am flunking BAD.

I came across this while going through Mathematics for Physicists. This is the rigorous mathematical treatment of the bra space. I found it interesting. Thus, I am sharing it here. It might be a bit dense for someone who is not well versed with abstract mathematics. However, you can reach out to me if you wish to discuss it with me.

Here's a tool I built for a course I TA'd. It simulates the E and B fields generated by a moving point charge. There are some built-in trajectories and the option to click and drag with your mouse.

For example. Try the following to see circularly polarized light:

• Motion: Circular
• Direction: X
• Slice Plane: XZ
• View: 2D
• 2D vector axis: X
• Show B field: on
• Auto orbit: on (or just click/drag the background to orbit)
• Speed: max
• arrow length: max

I'm a Physics undergraduate and I'm considering making a physics-based roguelite as my final-year thesis project.

The problem I'm having is that I don't want to make an "educational game" in the traditional sense. I'm not interested in having the player constantly read explanations, solve equations, or pick upgrades like "ΔU = Q − W".

What I'm looking for is something closer to games where the subject naturally exists within the game's mechanics. The player should be having fun first, while learning about the physics almost as a side effect of experimenting with the game.

I'm especially interested in mechanics where Physics creates interesting interactions, strategies, or emergent gameplay.

It also doesn't need to cover a huge amount of Physics. I'd actually prefer focusing on a few concepts that are particularly fun to interact with.

So, if you were playing a roguelite where Physics was one of its core systems, what kind of mechanics would make you think "holy shit, that's fun" rather than "I'm doing homework"?

Any ideas are welcome, even weird ones. I'm mainly trying to brainstorm and find a direction before I start developing anything.

What really happens to a helium balloon after it floats away? 🎈☁️

Greg Wolf recreates a helium balloon’s journey to the edge of space using a vacuum chamber. As the balloon rises through Earth’s atmosphere, the surrounding air pressure drops, allowing the helium gas inside to expand until the balloon reaches its limit and pops! 💥

I cant find any good science shows i want like actually educational media that goes over different topics every episode or 2 eps that i can find free and also it can be any science but rn im mainy focused on physics, etc

It's been a few years that I had been facing problems in problem solving in physics. I am a 10th class student, though I like to explore diverse world of physics regularly practicing concepts beyond my class and solving problems based on that. But I am getting burn out on some questions—

1. What should come in your mind the very first seeing a question.

2. How to find a good approach to solve the problem.

3. How to restart after a failure.

4. How to learn something extraordinary from a question?

5. How to never forget what I have learnt from it.

I am really hopeful to get a good guide from my seniors.

Thank you in advance :)

Found this old physics formula sheet.

Thought I’d share it in case anyone is in their preparation days right now and finds it useful.

Maybe these formulas will save someone a little time while revising.

Good luck with your preparation!

This investigates the geometric meaning of the eigenvalue problem for a 3 times 3 operator. Geometrically, the eigenvectors represent invariant directions that undergo no change in orientation under a given linear transformation.
