I am so thankful for your help haha, yeah I did.

No, I have no idea. But I have a feeling its got something to do with Centre of Mass? (which is something I can do-calculate the CoM; but I don't know if that's relevant). An earlier post mentioned something about the Parallel Axis Theorem-(but I have never come across this before) and I am...

Is it I=mr^2? (rotational inertia)

Apply an unbalanced torque to cause it to accelerate angularly-i.e. spin/rotate. (Newtons II Law). Oh okay, that's cool. Thanks-I believe I get this idea of rotational inertia better now. It's just that I have a hard time trying to actually calculate the rotational inertia (I guess you could...

I'm sorry, but my teenage brain is screaming/crying looking at that integral. Also, what is this 'roh' in the integral? I apologise @Nugatory if I come off as rude, but this is something that I haven't been taught yet. Do you think it's possible to learn all this derivative-stuff/integration...

Thanks for that, @tkyoung75 . My teacher was telling us that for this report that many assumptions would have to be made in order to help explain the physics concepts behind these rides at theme parks. So, since this rotational inertia of this gondola must be HUGE, then is that why an external...

Yes, you're assumption/idea of the ride is correct :) (sorry, I should have provided a video) video: (I believe only the first 10 seconds is enough) Anyways, if I take into consideration the axis that the gondola is rotating about then that would be the arm/pendulum-tube that the gondola is...

Picture of gondola: Formulae: Initially, I used the equation: I=mr^2 I=(6000)x(3)^2 T=54,000kgm^2 (but apparently this is incorrect) So, basically, I don't know which formula would suit best for the gondola (the picture above). I would consider the gondola a hollow object as the mass is...

Yeah, sorry about that @Nugatory . I wasn't thinking properly (I guess I was writing things down rather impulsively and without much thought). Originally, I was thinking about the land (which has the ice sheets on it) being in the water and what effect the melting of the ice sheets would have...

Yeah, I realized my mistake a couple of minutes after posting this. At the time I just posted my question without actually doing any research myself (you know those moments when you're just thinking about something & the obvious is right in front of you but you can't see it?... that's what I...

Ok, the water level would rise; because of the differing densities of the substances. I guess I should have thought more about that before posting this. Thanks for opening my eyes:)

I'm pretty sure that everyone knows that if you put an ice cube in a cup of water, and leave it for some time for the ice to melt, the level of water in the glass will not rise. (you could use that principle where that guy was in the tub and said "Eureka!" and then ran around naked). Now, my...

Wow. I can't believe it was this simple! I feel soo... stupid. Thank you @berkeman for clearing this up for me-it was a real eye-opener :)

So, I'm working on calculating the tension force in vertical circles-and I understand how to calculate the tension force at different points in the vertical circle (via vector sums). But what I don't really understand is how to interpret this information. What can I further do with these...

Hi @sophiecentaur I have only begun learning about 2D/3D vectors earlier this year, so this is all very new to me. Nevermind that-this is very good revision for me. Thanks :)
