The total path length covered by the object is 95 km, calculated as OA + AC (60 km + 35 km).

The motion is described using reference points such as O, A, B, and C to track the object’s position at different instants.

The simplest type of motion is motion along a straight line, which involves movement in one direction without deviation.

The total path length covered by the object is 95 km.

Yes, different reference points can be chosen based on convenience or relevance. However, once a reference point is established, it should remain consistent for describing positions in a particular context.
