← HistoryWhich limitation arose when medieval astronomers assumed uniform circular motion?
A)Errors in planetary position calculation✓
B)Inability to predict lunar eclipses
C)Discrepancies in stellar parallax
D)Inconsistencies within sundial timekeeping
💡 Explanation
Observed planetary motions are non-uniform; Epicycles were introduced to reconcile theory with observation, using the apparent retrograde motion, because uniform angular velocity was assumed. Therefore, the outcome was compounded error, rather than eclipses or stellar parallax inconsistencies.
