A skater glides along a circular path. She defines a certain point on the circle as her origin. Later on, she passes through a point at which the distance she has traveled along the path from the origin is smaller than the magnitude of her displacement vector from the origin.

Key Concepts: Circular Motion, Distance Travelled, Displacement Vector Explanation: When the skater defines a certain point on the circle as the origin, we can assume that she is moving along the circumference of the circle.\nThe distance traveled along the path is the distance that the skater covers along the circumference. Let's call this distance 's'.\nOn the other hand, the magnitude of the displacement vector is the distance between the origin and the point where she passes through.\nLet's call this distance 'd'.\nSo, the given condition is:\n s < d
