if i made up a frame that suspended a blade in the air would this be frame be showing centripital force? if i released the blade from the frame it would fall away from the frame. this to me is almost the same thing as the helicopter blade spining on the hub.
centripital force seems to be a silly way of understanding somthing so simple.
>what force sends the blade flying off on a tangent? inertia i would think.
if the hub was pulling the wheight of the blade in when its spinning, does this mean that if the blades were removed the hub would inplode?
a child on the play ground 'spining thing' holds a chain near the middle, centripital force stops her from flying off? true? now she drops the chain, does this chain pull itself in now the wheight is gone? now the little girl grabes the chain further from the centre. the chian is holding a hevier object now, can the chain pulling the little girl to the middle be actualy pulling, when it doesnt move if the girl is on or off it? why cant you just say the chain is holding her not pulling her inwards.
i think that you can call centrifugal force what you like and i think it is due to the movment and changing of direction which increases the weight of the object. eg a loop
the object doesnt have to be held from the middle, eg a car loop
when an engine is pinging the correct word is pinkin.
so centrifugal force is centripital. the way it works hasnt changed i just think the pulling to the centre bit is wrong.
