For simplicity we demonstrate this important principle for one-dimensional motion. Suppose that a b… Read more The Conservation Of Mechanical Energy

The word potential suggests possibility or capacity for action. The term potential energy brings to… Read more The Concept Of Potential Energy

We are now familiar with the concepts of work and kinetic energy to prove the work-energy theorem f… Read more The Work-Energy Theorem For A Variable Force

A constant force is rare. It is the variable force, which is more commonly encountered. Fig. 1 is a… Read more Work Done By A Variable Force

As noted earlier, if an object of mass m has velocity v , its kinetic energy K is  K = $\frac{1}{2}… Read more Kinetic Energy

As seen earlier, work is related to force and the displacement over which it acts. Consider a const… Read more Work
