    Zero angle if the initial and final positions of a ray coincide without making any revolution we say that the angle formed is zero angle.

    Assertion:If the magnitude of displacement is zero, then it is not a vector quantity. Reason : A vector needs both magnitude and direction

    Assertion: Distance is a actual length of the path but displacement is a shortest distance between initial and final position. Reason: Distance is a scalar quantity and it is always positive but displacement is a vector quantity. It may be positive, negative or zero.
