Michelle Dickerson, from Virginia 4-H, will be exhibiting at KTU in Feb.

The motion of an aircraft can be be explained by the physical properties defined in Sir Isaac Newton's Laws of Motion. The first law, often known as the law of inertia, states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. The second law defines the mathematical formula that for a constant mass, force is the product of an object's mass and its acceleration. The third law states that for every action, there is an equal and opposite reaction. The motion of an aircraft is driven by these laws. Using simple paper aircraft models, we will learn about these laws as they apply to aerodynamics and the forces of lift, drag, thrust, and weight.
