The everyday definition of work is defined as the way of transforming efforts in the form of energy from one object to another object. But the scientific definition of work is defined as the change in position of an object when a force is acting on it. Example: Using effort to solve a math problem is "work" in the everyday sense, but moving an object $5\text{ m}$ ahead with a force of $20\text{ N}$ is "work" in the scientific sense.
