Energy : the driving force

ENERGY : THE DRIVING FORCE 1.)Work: Work is the product of the force acting on the body and the displacement of the body. When the force (F) acting on the body and the displacement (s) of the body have the same direction, the work done by the force is W=Fs.   Work has magnitude ,but not dirction.   Thus, it is a scalar quatity. The SI unit of   work is the joule (J) and CGS is the   erg.      1jooule=1 newton *1 metre         1J =1Nm       1 erg =1 dyne* 1 centimetre                  = 1 dyne. centimentre        1 J = 10 ergs 2.) Positive , negative and zero work:When the force acting on the body and the displacement of the body have the same direction. When thhe force done by the force is ment have opposite directions, the force and displacement are perpendicular to each othe...
