Balanced and Unbalanced Forces: Calculating the Net Force

Activity 1 Read the instructions in the image and then answer the exercises. Draw a diagram for each scenario and solve 1. A boy pulls a wagon with a force of 6N to the right as another boy pushes with a force of 4 N to the left. What is the net force? 2. Mr. Smith and his wife were trying to move their new chair. Mr. Smith pulls with a force of 30 N while Mrs. Smith pushes with a force of 25 N in the same direction. What is the net force? 3. The classes are playing tug of war. Mrs. Larson's homeroom pulls with a force of 50 N. Ms. Mitko's homeroom pulls with a force of 45 N in the opposite direction. What is the net force? and who won? 4. Draw a picture below that shows an example of a balanced force (examples: a bird's nest in a tree, a hat on a person's head, or a light hanging from a ceiling). Show the forces acting on the object. In a separate picture show what would happen to the object if the forces became unbalanced. Read and answer the following 2 questions. Write your answer with your own words. What is a balanced force? What is an unbalanced force?
