Morphology
The phrase is transparently compositional: 'uniform' (not changing/same throughout) modifies 'acceleration' (change in velocity), so the meaning 'acceleration that remains the same over time' is directly derivable from the parts. This follows a regular adjective+noun pattern found across languages, so a B1 learner who knows both words will readily understand the MWE.
Etymology
Uniform acceleration shows a simple image: uniform means 'even' and acceleration means 'getting faster', like a toy car that gains the same amount of speed every second. So, it means 'speed changing at a steady rate'.
