hey, im really confused about something, im on the bit about units and dimensional analysis and the proportional stuff really stumped me, i havent seen it before i tried to follow it as closely as i could but im having issues visualising it particularly the final conclusion that d is proportional to s to the power of 3/2

unit is something defined with standard set in there for example length is meter is defined as meter length traveled by  or second as cesium atoms vibration  and we may derive other unit by measuring derivable quantity which upon the unit depend and dimension is the symbol on which the quantity can be expressed such as length as l time as T mass as M and always placed inside a third bracket for example force dimension is [ MLT-2]
And proportionality is a measure of two quantity where there is functional relation for example if we say force is proportional to acceleration is implies that if acceleration increased force will increased if decrease fore will decrease is directly proportional and the revers is inversely proportional .
