A prism will separate white light into a rainbow of light
Acceleration = vf-vi /t

The first law of thermodynamics is expresses by
D. ΔU=Q-W
which means change in internal energy of system = Heat added to system minus work done by the system
All are expressed in Joules.
This law is based on principle of conservation of energy.
That's the "Atomic Mass" of the atom.
