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

  1. I thought that m/s squared was a measure of acceleration not velocity.

    1. m/s2 is the unit for acceleration, not velocity :)

  2. What is Kilogram Meter / Second ??
    Kg m/s ??

    1. I think you might mean kg -m/s squared which is a newton (a measure of force). I hope that helps

  3. i thought that kg was a measure of mass? weight is measure in N because its a force i think :)

    1. kg is mass, but 'kg -m/s' the same thing as a newton (N) which is a measurement of force and weight :)

  4. What does Nm (newton metre) measure?
