Work is the transfer of energy, which may change the potential energy of a mechanical system, the thermal energy of a physical system, or the electrical energy of an electronic device. It is measured in joules (joule-kilogram-seconds).
In physics, the work done on an object by a force is the product of the magnitude of the force and the distance or displacement traveled by the object. This is defined as a scalar quantity, W, and it has the units of joule. The concept of work is a key element in the conservation of energy.
The simplest example of work is the frictional force between a sphere and a flat surface that causes the sphere to move. This is because the frictional force opposes the motion and does negative work. If the force is greater than or equal to the acceleration of the sphere, the force does positive work and increases the kinetic energy of the sphere.
Another important feature of work is that it is a vector quantity, meaning that it has a direction. If the force does not cause the object to move, it does no work, and if the force is perpendicular to the displacement of the object, it does negative work and decreases the kinetic energy of the object.
The concept of work is also a central principle in human resource management, which seeks to connect employees with the types of activities they enjoy and will find motivating. This is based on the premise that people are most satisfied and motivated when they are doing something they enjoy and can make a difference in. Companies that focus on connecting their employees with work they enjoy will be able to harness the power of talent to create an organization that is both competitive and resilient in an ever-changing world.
Redefining work isn’t easy, but it is necessary if organizations want to keep their employees happy and productive. As the workplace becomes more and more fluid, it is important to remember that the purpose of work is to help others and make a difference in their lives. It is time to reclaim the true meaning of work, and that starts with cultivating a culture of curiosity, connection and contribution that will help employees feel like owners. When this happens, organizations will be able to tap into the full power of their talent and truly make a difference in the world.
