Action (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠spotting a pattern shared by the field outside you and the field that you are, according to the Gestalt theorists.

A Form (n.) keeps ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠its shape when you add more of everything: double the charge on a conductor and the pattern of intensity does not budge.
