Background: The concept of force can be effectively represented on a graph using the Cartesian coordinate system. By representing four of the aeronautical forces (lift, drag, ,thrust ,weight) on a graph, students can visualize both parts of the definition of force:magnitude and direction. This lesson concentrates on the actual representation of the four forces on a graph. If, after combining the four forces, the net force is plotted in the upper right quadrant of the graph,then we will draw the conclusion that the airplane is able to fly.
Weight | 3 units |
Lift | 7 units |
Drag | 2 units |
Thrust | 5 units |
