a) Outline the essential problem with light, aether and the principle of relativity.

------------------------------------------------------------------------------------

ONLY PART (i) and (iii) for (b)

b) 'A frame of reference' is the object against which velocity is measured. The object such as the Earth or Sun provides a coordinate system for the purpose of assigning positions and times to events

(i) Contrast an inertial frame of reference with a non-inertial frame of reference

(ii) Describe what you would observe if you were to drop a coin in an aeroplane which is flying horizontally at a constant speed

(iii) Explain how the observation made in (ii) illustrates that the aeroplane is an inertial frame of reference

Step 1

Inertial frame of reference is a frame which is at either rest or uniform motion. Non-inertial frame is frame which will be in acceleration in a linear path or rotating in a uniform circular path.

In inertial frame of reference, the Newton laws are val...
