strength / force
'Kraft' and 'Wechselwirkung' can both describe something acting on something else. 'Kraft' is more about a single force, power, or energy that can move, change, or influence something. In physics, it is an influence acting on a body. 'Wechselwirkung', on the other hand, emphasizes that two or more things influence each other. So it is not just in one direction. Learners may confuse the words because both have to do with an effect or influence. A practical tip: 'Kraft' fits when something acts on something else; 'Wechselwirkung' fits when both sides react to each other or change each other.
