The only force being acted upon it is gravity. A ball that was thrown downward off a building isn't in freefall, because it had initial velocity. A piece of paper can't necessarily be in free fall because it is affected by air resistance.

Answer:
Explanation:
No.
There is a difference between energy, called heat in this case, and temperature, which is a measure of the amount of heat contained in a material and is dependent on the material properties.
Temperature difference is what causes heat to move from one body to another.
Two objects at different temperatures placed in contact with one another will cause heat to move from the warmer body to the colder body until the temperature difference is eliminated.
The amount of heat leaving the warmer body will exactly equal the amount of heat absorbed by the cooler body. (assuming isolated system of two bodies) The temperature change within each of those bodies could be vastly different.
Example would be a 2 mm bead of molten lead dropped into a liter glass of tap water. The lead may cool several hundred °C as it solidifies while the water temperature would increase less than 1 °C
