3.1 use the following units: degree (°), hertz (Hz), metre (m), metre/second (m/s), second (s)


degree (°)- distance
hertz (Hz)- cycles per second
metre (m)- distance
metre/second (m/s)- speed
second (s)- time

2.1 use the following units: ampere (A), coulomb (C), joule (J), ohm (), second (s), volt (V), watt (W)


Ampere (A)- current
Coulomb (C)- charge
Joule (J)- energy
Ohm (Ω)- resistance
Second (s)- time
Volt (V)- potential/energy
Watt (W)- power

1.1 use the following units: kilogram (kg), metre (m), metre/second (m/s), metre/second2 (m/s2), newton (N), second (s), newton per kilogram (N/kg), kilogram metre/second (kg m/s).


Bit of a self explanatory one here, but I thought of some things to say:

kilogram (kg)- the metric way of measuring weight; a standard bag of sugar is 1kg

metre (m)- the metric measure for distance; about one stride

metre/second (m/s)- this is a measure of speed; it is how many meters you go in a second

metre/second2 (m/s2)- this is a measure of acceleration, which is how quickly speed changes

newton (N)- a newton is a measure of force

second (s)- a second is how long it takes to say Mississippi (not scientific definition!) 

newton per kilogram (N/kg)- how much force for every kilogram of weight
