An object can gain kinetic energy by accelerating or gravitic energy by increasing height, among other things.
lose energy: gravity, otherwise see neuton's laws
When objects interact, energy is lost to friction in the form of heat.
An object gains energy when it is either heated or pushed. If pushed vertically, it gains gravitational potential energy. If pushed horizontally, it gains kinetic energy.
cold objects do have heat energy.
Thermal energy moves spontaneously from hot to cold objects.
No, objects that gain energy become hotter.

No, because they do not gain energy in falling.

Heat will naturally flow from hotter objects to colder objects. If heat flows OUT OF your body, you will LOSE that heat energy (thermal energy).
Think of energy as Mother Nature's money. Whenever something happens energy must be exchanged. Sometimes things gain energy, sometimes things loose energy, but it is neverdestroyed.Energy can be storedby objects (sort of like putting money in the bank). Eventually, however, this energy will be spent and passed on to some other object or objects.

They gain energy by eating food.
Thermal energy moves spontaneously from hot to cold objects.
energy is heat so more than cold objects
