Question

true or false

1. ______ a force is always only a push.
2. ______ rough surfaces create more friction, so more force is needed.
3. ______ force is always an interaction between two objects.

Explanation:

1. Forces can be pushes or pulls (e.g., tension is a pulling force).
2. Rougher surfaces have higher friction, requiring more force to overcome it.
3. By definition, a force requires an interaction between two objects (action-reaction pairs).

Answer:

1. False
2. True
3. True
