1) Under what circumstances is mechanical energy conserved?
Under what circumstances is momentum conserved? How is this different than the criteria for conservation of mechanical energy?
Homework Answers
Mechanical energy is conserved, if there is only conservative forces acting on the system. It will not be conserved if nonconservative forces acting on the system.
Momentum is conserved, if there is no external forces acting on the system. It will not be conserved if any conservative or nonconservative forces acting on the system.

C What is conserved in the following cases (linear momentum, angular momentum about an axis, mechanical energy, tionle kinetic energy, none of these)? There may be more than one conserved quantity. For this question, you do not have to show your reasoning (a) Two masses are released from rest, from the positions shown in the figure, in a frictionless hemispherical bowl. The masses collide and stick together. Note that the circular motion is characterized simultaneously by the linear and angular...

QUESTIONS: Is the mechanical energy remaining the same (conserved) with time? Is the decrease in the potential energy get completely converted into the kinetic energy? What is the cause of any mechanical energy loss in this experiment? Since energy is never really lost, what types of energy was this “loss” transferred into?
