Question

    What is the work done when a force of 10 N moves an

    object by 5 m in the direction of the force?  
    A 2 J Correct Answer Incorrect Answer
    B 15 J Correct Answer Incorrect Answer
    C 50 J Correct Answer Incorrect Answer
    D 5 J Correct Answer Incorrect Answer

    Solution

    Work W = F × d = 10 × 5 = 50  J    Work is only done when displacement occurs in the direction of the force.   If no movement, work is zero.   The unit of work is Joule (J).
