Yes, they are synonymous terms referring to the same mechanical device, though 'differential gear' is the more common word order.
Yes, in automotive and mechanical contexts, 'differential' is a standard short form for 'differential gear' or 'differential assembly'.
Nearly all cars with more than one driven wheel have a differential gear. Some very simple vehicles or specific machinery with a solid axle may not.
Its primary purpose is to allow the driven wheels on the same axle to rotate at different speeds, which is essential when the vehicle is turning, as the outer wheel travels a longer path.
A gear assembly in a vehicle that allows the driving wheels to rotate at different speeds, especially when cornering.
Differential gear is usually technical in register.
Differential gear: in British English it is pronounced /ˌdɪf.əˈren.ʃəl ɡɪə/, and in American English it is pronounced /ˌdɪf.əˈren.ʃəl ɡɪr/. Tap the audio buttons above to hear it.
Learning
Memory Aids
Mnemonic
Think of a car DIFFERing in its path when turning; the DIFFERENTIAL GEAR allows the wheels to handle this DIFFERence.
Conceptual Metaphor
A NEGOTIATOR between wheels: It allows cooperation (delivering power) while permitting independent action (different rotation speeds).
