If you are thinking on the atomic scale, we usually use the root mean square speed. On the macro scale this is reflected in the temperature.
(distance the object covers in some time) divided by (length of time to cover that distance) is the object's average speed during that time.

First radiation is the transmission of high energy particles. when you apply radiation to an object the energy from those particles is transmitted into the object. this additional energy is transmitted into the particle by "bumping" into the atoms or molecules that make up this object. by hitting those atoms with these fast moving particles you transmit that energy into the atoms of the object. this causes the atoms to move much faster than they were before. and the movement of these atoms contributes to the temperature of the object

Temperature is the measure of how fast particles are moving in an object.
All atoms have fast moving electrons. The warmer it is the faster the electrons is moving. But at -273,15 Celsius, no movement can exist.
This was the essential question on a homework assignment. Speed tells how fast an object is moving but it does not tell the direction. Velocity tells how fast an object is moving and it also tells the direction. When velocity is positive, the object is moving up. When velocity is negative, the object is moving down.
