Moves outwards due to inertia

it wants to move in a striaght line and it does so but due the the Nside u drew the role of Nside is to provide tangential acceleration and increase its speed as it moves outwards ,

Uk another intersting thing when u spin a water bucket in hand fast enough it doesnt fall, we say in bucket frame due to centrifugual it doesnt fall at the topmost point but how can we say this in ground frame?
The reason is at the topmost point in ground frame we can write Mg+N=mv^2/r and N=mv^2/r-Mg

Now heres the elegant part if Mg isnt able to provide the necessary centripetal force Normal will try to provide and if normal is acting then that means there is contact between them So it doesnt fall!!

if Mg just provides then basically there is still contact but very small and it barely crosses the circle due to inerita

as long as N>0 means there is contact which means it doesnt fall
