Newton's First Law of Inertia - Customization of Science Museum Exhibitions, Campus Community Science Popularization Equipment, Source Manufacturer of Science Exhibitions Description and Introduction of Scientific Principles:
This exhibition items demonstrate the inertia of objects through the combination of models and electromechanical interaction, allowing the audience to intuitively understand Newton's law of inertia. The exhibition items consist of a train model equipped with a ball throwing mechanism, a straight train track, an arch bridge model, an operating device, and a booth. Set up a rotary switch and start button on the exhibition stand to control the speed of the train. Press the start button to start and accelerate the train, and make a uniform linear motion when approaching the arch bridge. When the locomotive reaches the arch bridge, the car body throwing device throws the ball vertically, and the ball makes inertial motion in the horizontal direction and parabolic motion in the vertical direction. Therefore, after the train exits the arch bridge, the ball still falls into the ball hole.
