Best practice
Use "I knocked" to clearly indicate a physical action of striking a surface to gain attention. Ensure the context provides clarity on what was knocked on (e.g., "I knocked on the door", "I knocked on the table") to avoid ambiguity.

Avoid using "I knocked" when a different verb is more appropriate for the specific action. For example, instead of "I knocked the glass off the table", use "I bumped the glass off the table" or "I accidentally knocked the glass off the table" to convey accidental displacement more accurately.
