Toy cars can only run because they have motors. Today, we're going to make a car without a motor, but it can still run. Do you believe it? It's called the 'Sail Car'.
Why can he run without a motor? Let's explore the mystery together! The wind-powered car is a model car improved from the basis of a sailboat. It uses natural wind power as its source of energy, and its speed is closely related to the area and angle of the sail, the strength and direction of the wind, the weight of the car, and the resistance. The wind-powered car is composed of the body, the axle, and the sail. Its technological principle is: the sail is pushed by the natural wind, converting the wind energy into mechanical energy and transmitting it to the wheels, which overcome the friction resistance on the ground to roll. Now, for the new model of the wind-powered car, we've added a new feature, magnetic repulsion. Let's do an experiment together.
