The definition of work in physics reveals its relationship to energy whenever work is done, energy is transferred.. For a work to be done, in a scientific sense, a force must be exerted, and there must be displacement in the direction of the force. Causality (also referred to as causation, or cause and effect) is influence by which one event, process, state, or object (a cause) contributes to the production of another event, process, state, or object (an effect) where the cause is partly responsible for the effect, and the effect is partly dependent on the cause.In general, a process has many causes, which are also said to be Classical Physics hasnt been able to explain the dual behaviour of a matter and Heisenbergs uncertainty principle.
