My nieces like being pushed high in a basket swing. My sister-in-law worries they will fall out.
Assuming I don't push them above horizontal, that I don't catch the basket and stop it mid-swing, and that they don't deliberately abandon ship, might they fall out?
I suspect not, because the same forces act on the "riders" as on the basket - that is, gravity acting downwards and tension in the ropes acting towards the pivot. At any given position, whatever tendency the "riders" have to move in a given direction (including falling out when the basket is at its highest point), the basket will match.
Is that basically correct, or do I need to work on my physics as well as my child-care?
(This won't apply above horizontal, since both basket and occupant call fall, with occupant now beneath the basket.)
Edit: The basket is a large "part of a sphere" (don't know what that's called - shaped like a huge contact lens) - the diameter must be considerably more than a meter, and it easily accommodates two children with only the occasional foot protruding. Riding position is lying in the basket so CoG while inward of the basket, is only half-a-child-thickness inward. It doesn't have a small "seat" like a normal swing, which one might topple off.
