Unformatted text preview: The standard charge is called the statcoulomb. 7. A definition and rule for the calculation of work. 8. The amount of work required to bring object 2 from infinity to a distance r from object 1 when both have charge is (q 1 q 2 )/r . This work is called the potential energy. The sum of all the potential energies of all the pairs of objects in a system is the total potential energy. 9. The amount of work required to bring an object of mass m from no velocity to a final velocity of v is 1/2 (mv 2 ) . This work is called kinetic energy. The total kinetic energy of a collection of objects is the sum of all the individual kinetic energies. 10. If a system of objects is isolated from the rest of the world (universe) then the total energy, the sum of the total potential energy and the total kinetic energy, does not change as time changes....
