3. NET FORCE (Right) W. is a net force? How do we calculate net force?
3) What is the result of net force?
The combination of all forces acting on an object
2) When forces act in opposite directions- subtract the forces. The net force always acts in the direction of the stronger force.
When the forces are the same there is no net force.
3) Net force causes movement

4. Net force diagrams
Ex 1) What direction does the object move? Left- right: 100 N cancel out 150N – 50N = 100N arrow pushing up

5. Net force diagrams
Ex 2) What would be necessary to balance the forces? Left-right: Add 50N to the arrow pushing right or subtract 50N from the left Up-down: Add 25N up or subtract 25N down
