What is the point at which the net flow of thermal energy between two objects at the same temperature is zero?
When the temperature of the two objects is equal, the Thermal Flow will stop.
When will the flow of heat energy stop?
When the heat is traveling in the form of radiation, there's no reason for it to stop as long as the source is active. In the conductive and convective situations, the flow of heat from one material or object to the other stops when their temperatures are equal.
How is thermal eqilibrium achived?
Thermal Equilibrium is achieved when two objects reach the same temperature and exchange energy through heat. Eventually the temperature between the two objects will be equal and will stop exchanging heat. At this point, They are in a state of Thermal Equilibrium.
What are two effects of friction?
to slow down objects to a gradual stop and to cause a surface(s) to heat up.
When does thermal energy stop flowing?

What is the difference between a heat insulator and elctrical insulator?
an electrical insulator blocks the flow of electricity (like the rubber around power cords that stop you from getting electrecuted) and a heat insulator block the flow of heat (like a thermos)

Objects that stop the flow of electricity are good insulators what materials would be the best insulator for an electrical wire?
Plastic Tubing.

What is the major difference between conduction and radiation?
Conduction requires contact, radiation does not. Radiation in regards to thermodynamics is the straight line (line of sight) transfer of heat from a hot body to a cold body with no intervening fluid to convey that heat. Example: a flame will heat an object some distance from it by radiation as long as the transfer of heat is unobstructed. Place an object between the two and this flow of heat will stop. Conduction is the flow of heat between a hot body to a cold body by direct contact. Separate the two bodies and this flow of heat stops. Note: transfer of heat by an intervening fluid is convection. The hot body heats the fluid, then the fluid heats the cold body. All three forms of heat transfer occur in most practical heating applications.
Which keeps more heat fleece or soft leather?
The answer depends on air flow and if it's wet. Fleece has a higher R value, however it won't stop air flow by itself. Leather will stop air flow, however it does not have a very high R value.

Which property must be the same in order to stop the transfer of energy between two objects?
Temperature
What stops heat transfer?
If heat is being transferred by conduction, separating the two objects will stop heat transfer by that means.If heat transfer is by convection, stopping the flow of fluid between two objects will eliminate that means of heat transfer. One notable way of doing that is to interpose a vacuum between the two objects.If heat transfer is by radiation, the energy has to be sent out by the source and absorbed by the sink without interruption. If that can be interrupted then that can't happen. Some ways of achieving this areplace a non-transparent barrier between the source and sink - of course if the barrier absorbs the heat and then re-radiates it out the other side you still have heat transfermake the surface of the sink perfectly reflective - in which case no energy would be absorbed and thus no heat transfer would occur. Note that getting perfect reflectivity is impossible as far as we know.separate the source and the sink an infinite distance such that attenuation of the transmitted energy would reduce it to zero. Of course we don't have infinite distance to work with so that will only work for a thought experiment.Of course in all cases if the temperatures of two objects are the same, no heat transfer will occur no matter what mode of heat transfer you are considering.
Will friction stop objects from flying?
Yes, friction can stop objects from flying . . . unless the objects are moved by something stronger than the friction.
