WEBGalileo's experiment was a verifiion of the process of uniform acceleration. A rolling ball increased in velocity at a constant rate. This verifiion of constant acceleration is an instance of an object's inertia. In general, once an initial force is applied to an object, that force will continue until some other force acts against it.
