Answer:
A 1
Explanation:
Don't take my word for it because you did not include a photo of the diagram so therefore, I am answering this somewhat blindly with only the assistance of my prior knowledge. With this established, I believe that the answer is A 1 because potential energy is stored energy. Potential energy occurs in an object when it is not moving, in simple terms.
If 1 is the first stage of the rock over the waterfall, I would assume that it is at the very start of the process, perhaps beofore it has fallen over the waterfall? If this is the case, then the first stage is the stage with the most potential energy because the rock is still, containing stored energy.
The Point 1 is the point at which the rock will have the most potential energy when its falls over a waterfall.
A potential energy means a energy generated by an object because of its position relative to other objects.
Usually, these energy is highesr when the most energy is store dwhich is where the object reaches its highest point in the air before falling.
Therefore, the Option A is correct
