... Law of conservation of momentum: when no external forces act on a system consisting of 2 objects, the total momentum of the system before the collision = the total momentum of the system after the collision. Example: A baseball player uses a pitching machine to help him improve his batting average. ...

... CQ In Fig. 12.20, the plunger of a syringe is pushed in quickly, and the small pieces of paper in the syringe catch fire. Explain this phenomenon, using the first law of thermodynamics. (Similarly, in a diesel engine, there are no spark plugs. How can the air–fuel mixture ignite?) see Solutions W ...

... Use questions and answers to establish the knowledge of the group. We say that work is done by a force when the object concerned moves in the direction of the force, and the force thereby transfers energy from one object to another.

... • A compression is a point on a medium through which a longitudinal wave is traveling which has the maximum density. A region where the coils are spread apart, thus maximizing the distance between coils, is known as a rarefaction. A rarefaction is a point on a medium through which a longitudinal w ...

Chapter 5: Thermochemistry
... Essentially, the Law of Conservation of Energy: Energy can neither be created or destroyed but converted from one form to another. A system’s Internal Energy (E) = kinetic energy (KE) + potential energy (PE) of all the particles in the system. • While the values of KE and PE at a given instant are d ...
