    Solution:

    The given statement is true.
    Concept- In physics, we primarily discuss two sorts of quantities: vector quantities and scalar quantities. A scalar quantity is one that has no direction and simply a magnitude. A vector quantity is one that has both a direction and a magnitude.
    To begin, we must define scalar and vector quantities.
    Some physical quantities can be fully defined by their size alone. These are referred to as scalar quantities. Simple algebraic principles allow these quantities to be added or subtracted from one another. For example, body mass, body speed, and so on.
    However, there are some physical quantities that cannot be represented just by their size but also require some knowledge of their direction to be fully understood. Vectors are the names given to such quantities. For example, a body's velocity, acceleration, and so on.
    When we talk about work, we define it as the product of the force applied to a body and the displacement caused by the applied force. It is given mathematically as
    W=Fd
    Work is a scalar number since it merely has a magnitude and does not require a direction to be specified.
    Hence, the given statement is true.
