How does the loading machine toy demonstrate the concept of gravity?

The loading machine toy demonstrates the concept of gravity by the following:

• The toy demonstrates the force of gravity by the way it attracts the balls.
• The toy demonstrates the concept of inertia by the way it keeps the balls moving in a circular path.
• The toy demonstrates the concept of force and motion by the way it uses the balls to demonstrate the force of gravity.

The loading machine toy is a simple but effective way to demonstrate the concept of gravity. It is a classic demonstration that has been used for many years to teach about the force of gravity.
