How does the angular momentum of the rod (not the rod-clay system) change as the clay rod is at rest. A piece of clay collides with the edge of it and sticks, so they rotate together counterclockwise around the frictionless axle at the other edge. How does the angular momentum of the rod (not the rod-clay system) change as the clay collides?

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.
