KINDS OF SHIFTS
Each puzzle word passes the same exact test. The four mappings show how the answer works.
Doppler shift is the observed change in a wave's frequency caused by relative motion between source and observer.

Why this group was difficult
- The completed phrases belong to unrelated fields
Physics, work schedules, conceptual change, and vehicle controls provide little thematic overlap before SHIFT is found. - STICK has a persuasive physical interpretation
Its long, narrow shape makes it look compatible with several visible objects, delaying the compound-phrase reading.
How to spot this pattern next time
When four remaining words seem unrelated, place the same short word before or after each and listen for established expressions.
Treat a highly flexible word such as STICK as a warning sign: test its compound phrases before committing it to a visual group.
Four useful facts behind the group
- Doppler shift concerns an observed frequency change.
- Graveyard shift refers to overnight working hours.
