Question

question 3
what type of objects make good reference points?
○ moving relative to the earth
○ fixed relative to the earth
○ spatial relative to the earth
○ forceful relative to the earth

Explanation:

To determine good reference points, we need objects that are stable (fixed) relative to the Earth. Moving objects would not be good as their position changes, "spatial relative" is not a standard term for reference points, and "forceful relative" is irrelevant. Fixed objects relative to Earth (like buildings, mountains) provide consistent positions for measuring motion.

Answer:

B. fixed relative to the Earth
