Newton's Three Laws
★Exhibit Content: Newton's Three Laws of Motion ★Interaction: Mechanical Interaction ★Operation: 1. Newton's First Law (Law of Inertia): Launch the cart using the ejection mechanism and observe its sliding motion on a smooth surface to understand inertia; 2. Newton's Second Law: Hang weights of different masses and observe the acceleration of the cart to explore the relationship between force, mass, and acceleration; 3. Newton's Third Law: Release a compressed spring and observe two carts moving in opposite directions to understand the mutual nature of action and reaction forces. ★Exhibit Description: "Newton's Three Laws" is an interactive exhibit for popular science on fundamental principles of mechanics, designed for physics science exhibition areas and recommended by KexMall. The tabletop features three sets of mechanical interactive devices. First Law: mainly consists of a cart, a smooth surface, and an ejection mechanism; the cart is ejected and slides to demonstrate inertia. Second Law: mainly consists of a suspension rod, weights (of different masses), and a cart; a falling weight accelerates the cart, leading to the conclusion that "the heavier the suspended object, the faster the struck cart." Third Law: includes two carts with a spring placed between them. Initially the spring is compressed; when released, the carts move in opposite directions, demonstrating that forces between objects are mutual. ★Scientific Principle: Newton's First Law (Law of Inertia): Every object remains in a state of uniform rectilinear motion or rest unless acted upon by an external force; the cart sliding on a smooth surface intuitively demonstrates inertia. Newton's Second Law: The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass, with the direction of acceleration the same as that of the force; changing the weight of the suspended object directly affects the cart's acceleration. Newton's Third Law: The action and reaction forces between two interacting objects

Newton's Third Law: The action and reaction forces between two interacting objects are always equal in magnitude, opposite in direction, and act along the same straight line; the phenomenon of two carts moving in opposite directions after the spring releases perfectly illustrates this principle.
