1 pus 1 equals?

[CountessK]

Ok guys, I am not majorly inteligent but I have a query that has been bugging me for a while and need an answer- If we are to believe that everything is relative to the forces which act upon it and at what strength then there must be an instance whereby 1 measure's worth becomes more or less than 1, thus meaning 1 measure plus 1 measure doesn't equal 2 measures. If somebody could explain this to me I would be most grateful!!!

Let measure (whatever it´s supposed to be for now) be called m.

Now m -> m' < m

1m' + 1m < 2m

but:

1m + 1m = 2m

and (possibly more importantly):

1m' + 1m' = 2m'

 

In words: One "new measure" + one "new measure" = 2 "new measures".

 

Hope that helps.

I am not quite sure what you mean but if forces are added from different directions then they will not always add up to their linear sum.

 

In other words, if you and your friend are pulling an object with a force of 1 N, but you are pulling at right angles, then the object will move forward, at 45 degrees between you and your friend with a force of 1.4 N not 2 N.

 

I don't know if this is what you meant or not?
