What is the relationship between work and movement?

• A. Work requires force without movement
• B. Work occurs during any movement
• C. Work is done when force causes movement
• D. No work is done if there is no force

Answer: (C)

The concept of work in physics is defined as the amount of energy transferred by a force acting through a distance. Specifically, work is done when a force causes an object to move in the direction of that force. This means that both components – the application of force and the movement of the object – must be present for work to occur. In the context of the correct answer, when a force is applied to an object and it moves as a result, work is done on that object. For example, if you push a box across the floor, you are applying a force, and the movement of the box in the direction of that force means that you have done work on the box. Understanding this relationship helps clarify why other ideas, such as work occurring during any movement or work being defined by force alone without movement, do not hold true. Work specifically requires the interaction of force resulting in displacement. Therefore, whenever force and movement are in play, work is indeed being done, reinforcing the validity of the correct answer.
