Detailed explanation-1: -The correct answer is Force over a distance. Key Points. Work-It is a measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement.
Detailed explanation-2: -Work doneis defined as product of the force and the distance over which the force is applied. Workisdonewhen a force is applied to an object and the object is moved through a distance.
Detailed explanation-3: -What is Work? For work to be done, a force must be exerted and there must be motion or displacement in the direction of the force. The work done by a force acting on an object is equal to the magnitude of the force multiplied by the distance moved in the direction of the force.
Detailed explanation-4: -Definition, The work done by a force is the product of the displacement and the component of the applied force of the object in the direction of displacement. When we push a block with some force ‘ ‘ the body moves with some acceleration, work is done.
