Thank you all. I got my answer for my contrary-to-theory experience. These are the factors I gather: a wider base, a bigger reaction time, and a larger moment of inertia, play in favor of tall people (given all other factors like skill, where the force is applied (i.e the upper half), and weight...

But shouldn't 'flexibility/elasticity' have some role in here? At least it has always felt to me that way. The idea that tall things should be easier to fell assumes stiffness (e.g in case of trees). But with people, you have flexibility to account for too. I had one guy who was 6'1, 75 kg, and...

From practice (pls don't call police), I know that it is much easier to knock down short people. A tall person of equal mass is more difficult to knock down on the floor. Theoretically, the taller person should be easier because there's this whole center of gravity thing. But in practice, one...

Well, they'll be fine, yes, but who'll be hurt more? (I want to see things from 'pressure' point of view)

What about pressure? Talking only about the impact, say we eject a human and a wasp at the same speed in a vacuum and they hit a surface. Who'll be hit harder?

A wasp buzzes around my head and I'm annoyed. I smack it onto the floor where it is catapulted 2 meters down unto it. I watch the supposed corpse for about a minute and then I see that it is already up and about and ready to fly. How does it do that?? I imagine myself as a wasp-sized human. I...

Oh boy, I'm glad to have started this topic. Thanks for the great answers everyone. I've gotten the clarification I wanted.

Yes but it has been clarified by Jim Hardy to some extent. Thanks for the post. I have only one question remaining: The equation E = blv clearly tells us that if you keep on increasing the speed of the conductor, the electric intensity keeps on increasing -- is that true? This derivation (E...

Not used up as in 'consumed' but like, electrons shifted to one side to set up a p.d. Hard to explain my doubts because they're really going too outside the actual concepts (I can feel it already) so it might just be easier to simply tell me how p.d is actually set up. That might reveal something.

This question comes from the equation E = vB (moving conductor in a magnetic field -- E = electric intensity, v= speed of the conductor's movement, and B = magnetic field strength). Say B is constant, so the only thing we have to rely on to vary the electric intensity in the conductor is its...

Thanks a lot for clarifying.

But in opposite directions, isn't it? Pardon me but my mechanics suck

Sometime ago, in my partial state of sleepiness and being awake (you could call it trance - yo!) I had a thought that during perfectly elastic collisions, it's the deformation of the colliding particles which transfer energy from one to the other. But doesn't that assume that there are empty...

Isn't N canceled out by mgcos(x)?

Oh crap! My sleep deprivation must be taking its toll dammit. Thanks a lot man! I make the dumbest mistakes.
