related to thermodynamics.
Work done is a physical quantity that measures the amount of energy transferred when a force is applied to an object and it is displaced in the direction of the force.
Work done is calculated by multiplying the magnitude of the force applied to an object by the distance over which the object is displaced in the direction of the force. Mathematically, it is expressed as W = Fd, where W represents work, F represents force, and d represents displacement.
In thermodynamics, work done is a form of energy transfer that can occur between a system and its surroundings. It is an important concept in the study of thermodynamics because it allows us to understand the changes in a system's internal energy.
Yes, work done can be negative. This occurs when the force applied to an object is in the opposite direction of the displacement. In this case, the work done is considered to be negative as the energy is being transferred out of the system.
Some real-life examples of work done include lifting an object, pushing a cart, and using a bicycle pump. In all of these cases, a force is applied to an object and it is displaced in the direction of the force, resulting in work being done.
