Balanced and unbalanced forces are types of forces that affect motion. Which of the following statements is true about balanced forces?
They cause a change in the object's motion.
They do not cause a change in the object's motion.
They always act in the same direction.
They only occur in moving objects.
Is this picture an example of balanced or unbalanced forces?
Balanced forces, because they are using the same amount of strength on both sides, so there is no change in motion.
Unbalanced forces, because the amount of strength on one side is weaker than the amount of strength on the other, so there will be a change in motion.
