Although both e.m.f. and p.d. are measured in volts, they do not mean exactly the same thing. 1.15. Concept of E.M.F. and Potential Difference There is a distinct difference between e.m.f. and potential difference. The e.m.f. of a device, say a battery, is a measure of the energy the battery gives to each coulomb of charge. Whereas, The deferred operation of this act would tend to defeat its purpose, which is immediately to make appropriations for the fiscal year beginning July 1, 2012, and to make certain changes in law, therefore it is hereby declared to be an emergency law, necessary for the immediate preservation of the public convenience.

Newton's second law describes the affect of net force and mass upon the acceleration of an object. Often expressed as the equation a = Fnet/m (or rearranged to Fnet=m*a), the equation is probably the most important equation in all of Mechanics.

Chown, M., What a Star! New Scientist 162 (2192): 17, 1999. Our sun is very powerful and throws out flares every few years, usually around sunspot maximum. Other violent ejections called coronal mass ejections cause huge electric currents in the earth’s upper atmosphere and can disrupt power grids and satellites. One Newton unit of force is equal to 1-kilogram x 1 m/sec 2. Hence a bowling ball with a mass of 5 kilograms will exert a force of 5 kilograms x 9.8 m/s 2 or 49 Newtons. A beach ball with a mass of 2 kilograms will exert a force of 2 kilograms x 9.8 m/s 2 or 19.6 Newtons.
