    (i) • there is force applied to an objects

    • the object moves

    • the object moves in the same direction as the direction of the force

    (ii) workdone = force x distance

    = 23 x 34

    = 782Joules

    Answer:

    Question A1:

    Workdone=force x distance

    Question A11:

    7.82 joules

    Explanation:

    question A1:

    The relationship between work done, force and distance is that workdone can be calculated by multiplying force and distance

    Question A11:

    Force=23N

    Distance=34cm=0.34m

    Work done=force x distance

    Work done=23 x 0.34

    Workdone=7.82J
