hmm, does it have to do with concepts such as centre of gravity and moments? for example, the pivot is at the head, and there is a anticlockwise moment due to the centre of gravity and a clockwise moment due to the normal force at the feet?

Ok, so the trick is shown in the following link... could anyone explain how this is accomplished?

ahh... that makes more sense now. same thing for moments right?

I am just wondering why work done is force x distance and not, let's say force/distance. How did the idea of work done being force multiplied by distance come in the first place?

Hi all, Speed is a ratio of the distance traveled per unit time. But what then is work done and moments? For example, work done is force multiplied by the distance traveled in the direction of the force. But how would you explain the rationale of multiplying these two quantities? As...
