Register and Nuance
"力" is a common noun used in both formal and informal contexts. It is neutral in politeness but can be combined with polite verbs or expressions.
Common Learner Mistake
Learners sometimes confuse "力" with "強さ" (つよさ), which also means "strength." "力" often emphasizes the actual force or power, while "強さ" can refer more to the degree of strength or intensity. Use "力" when focusing on the ability or force itself.
