I'm curious about how an unrestrained slinky on a smooth surface would react to a steady pull. Could you explain the coil behaviour from the moment the pull begins until the entire slinky moves? Are there videos or resources that demonstrate this?

It's crazy. It also means that the mass in a system is conserved, right? Because the total mass of the system is 600g and then it splits into two scales: 400g and 200g.

I would like to see how you would integrate the sum of all the gravity forces on and towards every part of a hollow sphere I was thinking you could divide a sphere into like onion skins with cones and the cones would be sliced into sections it would be neat to integrate this and then calculate all the vectors and add them up and see what happens?

@dariuseversol Ай бұрын

I think this is incorrect, have you done all the math? and integrated the pull of gravity in all directions from a point inside a hollow sphere?? I think this is wrong totally wrong gravity is a localized phenomenon. it decreases by the inverse square of the distance

My cordless drill charger stopped working no LED’s displayed, I checked the resistor and it reads 00.5, there’s power going to the charger, but no LEDs lights up or charge the battery, is my resistor bad?

Want to ask if the heavy load side is pulled with a constant acceleration, what will happen to the scale reading would it increase or decrease? Sir can u make an example upon my question? 🙏

Thanks for this. I was able to do it from the front by using a 4" C-clamp. I opened it all the way, reached in to place the large (frame portion) of the clamp on the pin head, and then used the clamp to pull the pin into place. Just have to find a way to get a little more force on there than I could with my fingers. Pulling on the frame of the clamp gave me that. Might be able to do it with a nail puller too, just need that "L" shape.

I have a problem, why the wall does not have a vertical upward reaction force (vertical upward friction) in this case? Thank you.

@cstephenmurray 5 ай бұрын

The wall is frictionless, so there’s no “reaction force” possible there, if you are talking about Newton’s 3rd Law pairs. At the wall the 3rs Law force pair would be “the ladder pushing on the wall” and “the wall pushing back on the ladder”. These are normal forces which are always perpendicular to the surface.

When I measure ohm by fluke, it starts with a big number then goes down to a number. Why it does that? (e.g starts with 315.7 ohm then decrement down to 150 ohm)

@cstephenmurray Жыл бұрын

Hmmm. What are you measuring? If it is an actual resistor, then the only thing I can think of is that your connections were not secure and there was resistance in the connection. If it is a "non-ohmic resistor" (like a light bulb), then its resistance changes depending on current. As far as I know non-ohmic resistors would increase with current, but there could be others. If the connection is firm and you turn on the multi-meter and it fluctuates, then try another multi-meter. Those are my best guesses.

Another interesting aspect to consider, I think, is that galvanometer acts as a resistor. The further the needle is deflected, the greater the resistance. In order that equilibrium of circuit be sustained, coil must turn within magnets, inducing a counter-current in the coil.

Which is one positive, and which negative, is a convention for the sake of being consistent. Which way current is "flowing" is a matter of how one visualizes current.

Thank you! The zero gravity in the "hollow Earth" makes perfect sense, even without calculus. Or maybe more so intuitively without calculus. That's the next step. But what about gravity when r < R? | r is really (r/R). That's probably self evident to your pupils in your classroom, but not to everyone watching your videos. But I understand if you don't want to be over-pedagogic before your pupils.

I'm struggling to understand why there is no normla force of the ladder on the person, or if there is why it's not included in the free body and any of the calculations?

@cstephenmurray Жыл бұрын

Another omission by me, sorry. I SHOULD have started by defining my system. In this case I used the combined system of Slim Jim and the ladder. As a result the normal forces between them are internal forces and can be ignored. If our system was defined as just the ladder, then Slim Jim does apply a normal force to the ladder. Since Slim Jim is also at static equilibrium, so mg = Fn for Jim, then, by Newton's 3rd Law, Fn of Jim on the Ladder also equals mg of Jim. Hope that helps.
