Work-Energy Principle

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Work-energy principle, abbreviated as \(W_{net}\), is the change in the kinetic energy of an object is equal to the net work done on the object.

Work-Energy Principle formula

\(\large{ W_{net} = \frac {1}{2}\; m \; v_f^2 -\frac {1}{2}\; m \; v_i^2  }\)         

Where:

\(\large{ W_{net} }\) = net work

\(\large{ m }\) = mass

\(\large{ v_f }\) = final velocity

\(\large{ v_i }\) = initial velocity
