Net Forces

Master net forces! Solve problems on balanced & unbalanced forces. Great for science practice.

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 N 45 N 10 N 2. When two forces are acting on the same object in OPPOSITE directions, you subtract the forces.12 N - 10 N = _ 22 N 12 N 2 N =============================================================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? net force is 600 Nthe box will not move net force is 200 Nthe box will move to the right net force is 200 Nthe box will move to the left. net force is 600 Nthe box will move to the left -------------------------------------------------------------------5. In the diagram 2 people are pushing books. What is the net force being applied to the books? 25 N 5 N to the right 5 N to the left zero, the forces are balanced -----------------------------------------------------------------6. In the diagram two people are pushing books. What is the net force being applied to the books? 21 N 19 N to the right 19 N to the left zero, the forces are balanced _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 is stronger than the boy.
