Work & Energy

064 - Work and Energy In this video Paul Andersen explains how the mechanical energy added or removed from a system results from work. For work to occur a force must act parallel to the displacement of the system. Since work and energy are equivalent the work-energy theorem allows of for calculating the work as the change in kinetic energy.

Paul Andersen explains how the mechanical energy added or removed from a system results from work.  For work to occur a force must act parallel to the displacement of the system.  Since work and energy are equivalent the work-energy theorem allows of for calculating the work as the change in kinetic energy.  A force-displacement graph can be used to calculate the work done on the system.
