Why do some yoyos feel heavier than others?
Have you noticed it? Sometimes you grab a yoyo that it's even smaller in size and has a lower mass than another and yet it feels heavier and plays differently. Why is that? The short answer: Density, the long answer: It gets interesting. Ok, I think the first thing I should do is to clarify that I'm not a physicist. I'm just a software engineer that happens to like yoyos and that still remembers some of what I learned at university. Also, I know my theory is subjective, maybe you feel different but hey, that's what the comments section is for! :D With that out of the way, let's start. By definition, density is mass per unit of volume, its formula is D = m/V. What does that mean for us? It means that the bigger the yoyo (the greater the volume), the lighter it will feel... well, that's a bit simple but it's the general idea that's behind this...
