Universal Gravitation
★Exhibit Content: Gravity, Gravitational Force ★Interaction: Mechanical Interaction ★Operation: Place the small ball along the track into the funnel and observe its trajectory. ★Exhibit Description: The exhibit consists of steel balls, a steel ball recovery device, a circular track, etc. After visitors throw the steel balls one by one along the tangent at the edge of the funnel, under the action of gravity, the balls move in elliptical trajectories along the funnel-shaped 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 at the edge of the funnel, under the action of gravity, the balls move in elliptical trajectories along the funnel-shaped surface with the center of the funnel as the focus.
