Origami helicopter is a simple toy that can be made by folding a piece of paper into a specific shape. When dropped from a height, the helicopter spins as it falls, due to the aerodynamic properties of its design. Origami helicopters rely on principles of aerodynamics and paper engineering to achieve flight. The helicopter blades are designed with a curved surface that creates lift when they rotate, while the weight of the paper and the design of the body create stability during flight. The angle of the blades and the speed of rotation also affect the lift and stability of the helicopter. The shape and size of the paper used in the origami design can impact the overall flight characteristics. In addition, the mass distribution of the helicopter affects its motion. The weight of the helicopter is concentrated in the bottom part of the design, which creates a stable center of gravity. This stability allows the helicopter to spin evenly and smoothly as it falls.
