Non-uniform Motion

Explanation:

Though the boy maybe walking with a constant speed, its velocity is not constant . The type of motion is determined by the velocity and not the speed of the object.

The velocity is a vector quantity. This means it has two parts :

  • Magnitude
    Which, in this case is the speed #0.5 "km"/"min"#.

  • Direction
    Which, in this case keeps changing .

    As you can see in the diagram, at point A, the direction of his velocity is different from the direction of his velocity at point B.

Thus we can conclude that for an object to be traveling in uniform motion, the magnitude AND the direction of its velocity must remain unchanged.
