Most hiccups will stop on their own. Home remedies are generally sufficient to resolve hiccupping. For persistent hiccups (lasting more than three hours) treatment varies, and you may need to contact your doctor. A physician may prescribe medications for severe, chronic hiccups.
In physics, a force is said to do work if, when acting, there is a displacement of the point of application in the direction of the force. For example, when a ball is held above the ground and then dropped, the work done on the ball as it falls is equal to the weight of the ball (a force) multiplied by the distance to the ground (a displacement). Work transfers energy from one place to another or one form to another.
Updated May 26, 2014. Definition: Work is defined (in calculus terms) as the integral of the force over a distance of displacement. In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by that force. Though both force and displacement are vector quantities, work has no direction due to the nature of a scalar product (or dot product) in vector mathematics.
