Heat can only be transferred if there IS a temperature difference. (If two objects have the same temperature, nothing will happen).
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 is heat because temperature is being transferred
When objects collide or touch, kinetic (mechanical) energy can be transferred.
Since temperature is a measure of kinetic energy, so as kinetic energy decreases, temperature must also decrease.

(thermal) equilibrium
It's not. A difference in temperature is required in order to drive the transfer of heat.
Heat energy will be transferred from the hotter objects to cooler objects until they are all at the same temperature.
