Scientific Enlightenment:

Today, we're going to make a wind-powered car. Let's explore together!

Experimental Purpose:

1. Understand the working principle of a wind turbine.
2. The action of force is mutual.

Experimental Cognition
The action between two objects is mutual. When one object exerts force on the other, the other object also exerts a force in response, and these two forces are mutually called action force and reaction force. The size of the action force and the reaction force is always equal, and the direction is always opposite, acting on a straight line. When a person pushes against a wall, the force is the action force, and the wall will also give you a force of the same size, which is the reaction force. Row a boat, swim, and fly a spaceship are based on this principle. When you hit the table with your hand, your hand will hurt, and when you throw a table football forcefully on the floor, you will find that the harder you use, the higher the table football will jump.

Science Expansion:

1. Interaction forces are equal in magnitude, opposite in direction, and act on two different objects along the same line; the nature of the two forces is the same.
2. Balanced forces are two forces acting on the same object, of the same magnitude but in opposite directions, and acting along the same straight line. The nature of the two forces can be different.
3. Two forces that are in equilibrium can exist separately, and they are produced and disappear simultaneously when interacting.
4. The interaction force only involves two objects (the object applying force is also the object experiencing the force), while the balancing force involves three objects (two applying forces and one experiencing the force).
5. Interaction forces act on two separate objects, while balanced forces act together on one object.
6. Interaction forces do not have a net force, while balanced forces do.
7. Interaction forces have their own effects, while balanced forces have common effects. Based on the nature of forces, they can be classified into elastic forces, friction forces, and gravitational forces, etc. The action forces and reaction forces between objects always belong to the same type of force. For a pair of action forces and reaction forces, it is not correct to say that one force is the cause and the other is the result. Either of the two forces can be considered as the reaction force, and the other one, relative to it, becomes the reaction.
