Detailed explanation-1: -Work is done when a force is applied to an object through a distance. This means that when a force is applied to an object through a distance, the object’s total energy will be affected.
Detailed explanation-2: -The work W done on an object by a constant force is defined as W = F·d. It is equal to the magnitude of the force, multiplied by the distance the object moves in the direction of the force.
Detailed explanation-3: -If the applied force causes an object to move to a distance, work is said to be done.
Detailed explanation-4: -If a force is applied but the object doesn’t move, no work is done; if a force is applied and the object moves a distance d in a direction other than the direction of the force, less work is done than if the object moves a distance d in the direction of the applied force.
