Abstract

- What happens to a liquid in a swing or a loop? Accelerated motions leadto effects that may seem surprising. Consider a liquid in a glass placed ona wooden triangle, in turn attached to a string and moving fast in circle a vertical plane. The surface of the water remains parallel to the bottom of the glass—and orthogonal to the string—as long as gravity and the tension in the string are the only forces acting on the triangle. A key to the understanding is that the tangential acceleration of the liquid, the glass and the triangle, are all identical to the tangential component of the acceleration of gravity.
