The term 'work' in mechanics is defined as the product of force applied to an object and the distance over which that force is applied, especially when the force and the direction of motion are aligned. This concept is crucial because it quantifies the energy transfer that occurs when a force acts upon an object to move it.

When you apply a force to an object and it moves a certain distance in the direction of that force, work is done. The formula for calculating work is given by the equation W = F × d, where W represents work, F represents the force, and d represents the distance moved in the direction of the force.

Understanding this definition is essential for solving various mechanical problems, as it helps determine how much energy is used or exerted in moving objects. The other options do not accurately reflect the physics of work. For example, while the amount of force applied relates to work, it does not encompass the distance aspect, which is crucial for its definition. Similarly, energy stored in an object and the speed of an object pertain to different physical concepts and do not encapsulate the definition of work in mechanics.
