What is the special case of conservation of mechanical energy?
In this post, we apply the special case of conservation of mechanical energy to the quantitative analysis of motion, as a part of the Prelim Physics course under the module Dynamics and sub-part Forces, Acceleration and Energy. We take a look at the work done and the change in the kinetic energy of an object undergoing accelerated rectilinear motion in one dimension W = F||s = Fscos(\theta) , and the changes in gravitational potential energy of an object in a uniform field \Delta U = mg \Delta h . Mechanical energy, E_{M} , is the sum of the potential energy and kinetic energy in a system E_{M} = GPE + KE
The following videos will guide you through work and energy, including gravitational potential energy and the related equations and theory-based around the special case of conservation of mechanical energy.
