Heat
If two objects of different temperature are brought into contact, internal energy is transferred via heat. If two objects collide, kinetic energy is transferred between them.

It's not. A difference in temperature is required in order to drive the transfer of heat.

it is heat because temperature is being transferred
If those two objects are in contact with each other, they will come to thermal equilibrium, at a temperature some place between the original temperature of the two objects. The actual final temperature will depend on the specific heat capacity of each object, the mass of each object and the temperature of each object.
Heat can only be transferred if there IS a temperature difference. (If two objects have the same temperature, nothing will happen).
Heat is the amount of energy transferred between objects where a difference in temperature is present. So in that sense, heat is related to temperature differences, but is not the same. The temperature difference is caused by the difference in the avg. speed of particles between the two objects.
Radiation
Temperature is a measure of the heat energy of objects, and heat is the energy transferred from a high temperature location to a low temperature location.When two objects are in contact, heat always flows from the warmer object to the cooler object by conduction, until thermal equilibrium is established and the heat transfer stops (becomes the same in either direction). The transfer of heat continues as long as there is a difference in temperature between the two points.
Heat is not the transfer of thermal energy. Heat is the thermal energy. What drives itacross a boundary between substances or objects is a difference in their temperatures.
