work com work defines the product of the intensity of a force by the distance it travels is symbolized w = f. d
cgs (W) = dyn. cm = erg (erg)
MKS (W) = N. m = J (Joule)
technician (W) = Kg force. m = (kilogrameter)
relations between units kgm = kg force per meter is equal to 9.8 newtons per meter
kgmes
equal to 9.8 J J = Newton per meter = 100000 dyn. 100cm
J = 10000000 = 10 erg to erg
seventh kgm = kg force per meter = 980000 dyn cm per 100 kgm
= 98,000,000 ergs = 9.8 for the seventh erg

work gravitate gravitational work is called the work done by the weight of an object to travel a certain height. gravitotorio at work does not take into account shifts in a Horizontally
W = weight. h
Power Power is defined as the ratio of work performed and time spent doing is symbolic power
P = work / time
P = W / t
cgs units (P) = erg / sec
MKS (P) J / sec = watt
technician (P) = kgm / s;
cv cv = 75 km / sec
