The work done on an object due to a force is represented by the formula W = Fs, where W is the work, F is the force applied, and s is the displacement in the direction of the force. This formula indicates that work is calculated by multiplying the force exerted on an object by the distance the object moves as a result of that force. It is important to note that the displacement must be in the same direction as the force for the work to be considered effective; otherwise, the work done would be zero if there were no movement in the direction of the applied force.

Understanding this formula is fundamental in physics, particularly in mechanics, as it helps illustrate the relationship between force, movement, and energy transfer. In practical applications, recognizing how much work is done when a force is applied can impact safety assessments, such as evaluating the risks of lifting heavy objects or operating machinery. This principle can aid safety professionals in designing safer work environments and procedures.
