The scientific definition of work refers to the force applied to an object causing its displacement in the direction of the force. In everyday language, work typically implies any physical or mental effort exerted to achieve a task, regardless of displacement.

Living beings and machines both require energy to perform work. They convert energy into different forms to power their functions: living beings metabolize food, while machines typically use fuel or electricity.

Engines require fuel like petrol and diesel to undergo combustion, which releases energy. This energy is converted into mechanical work, powering the engine's movements and enabling the operation of vehicles and machinery.

No work is done on the load when you stand still with it on your head because, according to the scientific definition, work requires displacement in the direction of the applied force, which is absent in this scenario.

Standing still for a few minutes with a heavy load on your head results in tiredness and energy expenditure. However, according to the scientific definition of work, no work is done on the load as there is no displacement.
