Doppler Effect
The Doppler Effect arises whenever a source of waves is moving in relation to its observer or an observer is moving in relation to the source of waves. The result is that the waves will have different wavelengths and frequencies than expected. When a source of waves approaches an observer, the waves crunch up meaning that from the observer’s view point, the waves have shorter wavelength and a higher frequency. As a source of waves recedes from an observer, the waves stretch. This means from the observer’s viewpoint the waves have longer wavelength and lower frequency.

1 eV (electronvolt) = x Joules
1.6x10-19 J
In physics, an electronvolt is the amount of kinetic energy gained (or lost) by a single electron accelerating from rest through an electric potential difference of one volt in vacuum.

Translational Equilibrium
An object is in translational equilibrium when the sum of all the external forces acting on the object equals zero. This also means an object is in translational equilibrium when it is experiencing zero overall acceleration. Therefore, it is either not moving or moving at a constant velocity.
Gauge Pressure
for example, if you have a tire at atmospheric pressure, a gauge measures it as 0; any measurement is a result of a pressure GREATER than the atmospheric pressure. thus:
gauge pressure + atmospheric pressure = total pressure exerted.
