Universal Gravitation
★Exhibit Content: Gravity, Gravitational Force ★Interaction: Mechanical Interaction ★Operation: Press the start button, the ball is lifted and then placed into the funnel along the track, watch the ball's trajectory. ★Exhibit Description: The exhibit consists of a steel ball, steel ball recovery device, steel ball lifting structure, disc track, etc. After the steel balls are thrown one by one along the tangent of the funnel edge, under the action of gravity, the balls move in elliptical trajectories along the funnel-shaped curved surface with the center of the funnel as the focus, vividly simulating the motion of planets around the sun in the gravitational field of the solar system. ★Scientific Principle: There is a gravitational force between any two objects in the universe. The magnitude of the gravitational force is inversely proportional to the square of the distance between them and directly proportional to the product of their masses. When the steel balls in the exhibit are thrown one by one along the tangent of the funnel edge, under the action of gravity, the balls move in circular motion along the funnel-shaped curved surface with the center of the funnel as the focus.
