The Inertia Apparatus is a physics laboratory instrument used to demonstrate the concept of inertia, which is the tendency of an object to resist a change in its state of motion. The apparatus consists of a metal frame with two metal balls or cylinders mounted on opposite ends of a horizontal rod.

To use the apparatus, the frame is held by one end, and the other end is struck with a sharp blow. The impact causes the frame to rotate around its pivot, and the metal balls or cylinders remain stationary due to their inertia. This demonstrates the principle of inertia, which states that an object at rest tends to stay at rest, and an object in motion tends to stay in motion unless acted upon by an external force.

The Inertia Apparatus is widely used in physics education, from high school to university level, to teach the principles of mechanics and the behavior of objects in motion. It provides a simple and effective way to demonstrate the fundamental principles of physics and helps students to develop their problem-solving and critical-thinking skills.
