I was beginning to wonder if scientific notations and the meaning of scientific words had changed since I went to school, so I found one of the old text books that I used to study, there I found the following information:
1 meter=100cm., and 1 kilogram =1000 gm., the unit of energy on the M.K.S system will be (1000) (100)2 = 107 ergs. This unit is called a joule.
In the M.K.S system, unit work = 1 meter. Newton =1 joule.
In the M.K.S. System, unit power is 1 joule per second.
1 kilowatt = 1,000 watts = 103 joules per second.
Then I looked in a modern dictionary and found this reference to power.
watt (wòt) noun
Abbr. W
Electricity.
An International System unit of power equal to one joule per second.
[After James Watt.]
Are these books wrong, am I wrong or is R.L. Wrong?
After all if the quantity of energy and power are the same, then why can they not be interchanged? (even if not done in error)
Cheers
