Food Additive Allergy -- tartrazine: A tartrazine allergy is an adverse reaction by the body's immune system to tartrazine which is used as an additive in a number of foods (some breakfast cereals, cake mixes, chocolate chips etc.) The specific symptoms that can result can vary considerably amongst patients and may range from mild to severe.
The equation form of Newton's second law allows us to specify a unit of measurement for force. Because the standard unit of mass is the kilogram (kg) and the standard unit of acceleration is meters per second squared (m/s2), the unit for force must be a product of the two -- (kg)(m/s2). This is a little awkward, so scientists decided to use a Newton as the official unit of force. One Newton, or N, is equivalent to 1 kilogram-meter per second squared. There are 4.448 N in 1 pound. So what can you do with Newton's second law?
the word you are thinking of is joules (symbolized by J), but that's not what force is measured in. force is measured in newtons (symbolized by N). here are the definitions of the two words: + one joule is the work done, or energy expended, by a force of one newton moving one meter along the direction of the force. + the newton is the unit of force derived in the SI system; it is equal to the amount of force required to give a mass of one kilogram an acceleration of one meter per second squared.
