Work Power and Energy worksheet with Answers-Physics About In the cgs systems, the unit of work is 1 dyne centimeter, called 1 erg.Using the relations between the newton,dyne,and pound ,and between the meter,centimeter,and foot,we obtain 1joule =10 7 ergs =0.7376 ft.1b.Work is a scalar, although the two quantities involved in its definition, force, and displacement, are vectors.

PDF Topic 5: Work and Energy - Fermilab Topic 5: Work and Energy Worksheet (A) WORK is accomplished when a force moves an object through a distance. Energy is added to a system when an external force moves a body. We can say that work is one form of energy. When a force acts from within a system, energy is removed from the system. One example is stretching a rubber band.
