Positive non-conservative work | Problem In a system where positive non-conservative work is being down on the system, which of the following statements are necessarily true? If the kinetic energy is decreasing, the potential energy must be increasing by the same amount. If the kinetic energy is decreasing, the potential energy must be increasing by a larger amount. If the kinetic energy is increasing, the potential energy must be decreasing. If the kinetic energy is constant, the potential energy must...

We know that there is a relationship between work and mechanical energy change. Whenever work is done upon an object by an external force (or non-conservative force), there will be a change in the total mechanical energy of the object. If only internal forces are doing work then there is no change in the total amount of mechanical energy. The total mechanical energy is said to be conserved. Think of a real-life situation where we make use of this conservation...

Learning Goal: To understand how to apply the law of conservation of energy to situations with and without nonconservative forces acting. The law of conservation of energy states the following: In an isolated system the total energy remains constant. If the objects within the system interact through gravitational and elastic forces only, then the total mechanical energy is conserved. The mechanical energy of a system is defined as the sum of kinetic energy K and potential energy U. For such...
