Question

Resistance of force of equal magnitude acting in the opposite direction to an action force. a inertia b reaction c motion d unbalanced force

Answer 1

D

Step-by-step explanation:

Unbalanced forces cause an object to start moving, stop moving, or change direction. Unbalanced forces acting on an object will change the object's motion. ... Equal forces acting in opposite directions are called balanced forces. Balanced forces acting on an object will not change the object's motion.
