Final answer:
An object can indeed travel a distance of 10 km and still have a displacement of 0 km, which can happen when the object returns to its original starting point.
Step-by-step explanation:
It is indeed possible for an object to travel a total distance of 10 km and yet have a displacement of 0 km. This scenario can occur if the object returns to its starting point after moving. Displacement is a vector quantity that refers to the change in position of an object, having both magnitude and direction. In contrast, distance is a scalar quantity that only measures how much ground an object has covered during its motion, without considering the direction.
For example, imagine a person walking in a big circle and arriving back at their starting point. The path they walked along might have been 10 km long, so they traveled a distance of 10 km. However, because they ended up where they started, their displacement is 0 km, since there is no net change in position.
