Question

An objects position is always defined relative to a reference point. If the object changes position, its motion can be described as moving in some direction in relation to this reference point.
If the relative position of a diver Is begin described as below a certain reference point midway through a dive, what reference point is most likely being used

A. The bottom is the swimming pool

B. The diving board

C. Other swimmer in the water

D. The far side of the swimming pool

Answer 1

The position of the diver is described as "below a certain point"; therefore, the reference point must be above the diver. For a diver in the middle of his dive, the bottom of the pool, the other swimmers and the far side of the swimming pool are likely to be below the diver, or at level with the diver at most. Out of the options, the only point of reference that is likely to be above the diver is B. the diving board.
