Net Forces textbook pg. 54-56

Master net forces! Calculate forces, identify balanced vs. unbalanced, and predict motion with our fun worksheet.

1. When two or more forces are acting on the same object, in the SAME direction, you ADD the forces.25 N + 20 N = _ 5 Nright 45 N right 5 Nleft 45 N left 2. When two forces are acting on the same object in OPPOSITE directions, you subtract the forces.12 N - 10 N = _ 22 N right 22 Nleft 2 Nright 2Nleft =============================================================3. When forces are BALANCED, the net force is _. zero (0) To the right To the left 4. A big tractor pulls a box with a force of 400N to the left. A small tractor pulls that same box with a force of 200N to the right. What is the net force on the box and what direction will it move? 600N,the box will not move 200N,the box will move to the right 200N,the box will move to the left 600Nthe box will move to theright --------------------------------------------------------------5. In the diagram 2 people are pushing books. What is the net force being applied to the books? 25N to the right 5N to the right 5N to the left 25N to the left -----------------------------------------------------------6. In the diagram two people are pushing books. What is the net force being applied to the books? 21Nto the right 19N to the right 19N to the left 21Nto the left _7. The net force is 7 NAre the forces balanced or unbalanced? unbalancedWhich direction would the cart move? to the right 8. The boy in the picture is trying to pull a dog on its leash, but the boy and the dog are moving in the same direction. Which of the following best describes this situation? The forces are balanced and the net force is zero. The forces are unbalanced and the boys force is greater. The forces are unbalanced and the dog's force is greater. The forces are balanced and the dog's force is greater.
