Fundamental Units and Compound Units

Fundamental Units used in Physics looked at and how they combine to make up all the other units used in Physics.
Fundamental Units covered in detail were:

• Time - t (seconds - s)
• Displacement - d (meters - m)
• Mass - m (kilogram - kg)
• Electric Current - I (Amp - A) { NB: this multiplied to time makes Charge - Q, q (Coulomb - C) which one would think is the more logical fundamental unit. The reason is due to how we measure Current}

There are three more to do with Temperature, Amount of a Substance and Luminous Intensity which are not dealt with at this level.
