Answer 2

Answer:

Force is an interaction between two or more bodies that when unopposed causes a change in the state of motion of the objects. So in the definition of force itself, it explicitly states that force is something that causes a change in the state of motion. Interaction of forces can also be thought of as a push or a pull.
