    Undergrad Can Humans Create Rotational Motion of Water Using Their Own Electric Field?

    Hi everyone! I wanted to know if there is a possible way for a human-being to create a rotational motion of water in a metallic box by himself, probably using his own electric field (is there such a thing?) with no other accessories? It might be related to the term "Electric people"...

    How Does a Man Walking on a Merry-Go-Round Affect Its Motion?

    I thought so... but shouldn't there be any torque? If there is a conservation of angular momentum than there is no torque acting on the marry-go-round, means there is no friction between the man and the marry-go-round... but if there is a torque (and thus a friction) than you don't have a...

    How Does a Man Walking on a Merry-Go-Round Affect Its Motion?

    1. A man with mass m walks with a constant velocity v with respect to the ground on the edge of a marry-go-round that has a radius of R and moment of inertia I. The system starts from rest. a) what is the angular velocity of the marry-go-round? b) when the man completes a full cycle (returns...
