Identifying centripetal force for ball on string (video) Khan Academy
F_ty + F_g = 0. F_ty = F_g. That last equation shows that the vertical component of the force of tension is equal in magnitude, but opposite in direction, to the force of gravity. There isn't a normal force because normal force requires contact with a surface. In that second example, the ball on the string is just moving through the air.
