I created this net forces worksheet to help my students practice finding the net force and to determine whether forces are balanced or unbalanced. For the first 15 questions, students draw a free body diagram to describe the forces acting on an object. Then, they determine the magnitude and direction of net force and describe whether or not the object's velocity is affected. For the last 5 questions, student summarize how balanced and unbalanced forces affect an object's motion. I hope this lesson will help your students visualize and clearly distinguish the difference between these two net forces.
