PURPOSE:To perform a smooth initial shift of a robot from its initial position to the working start position by providing a total distance calculating means, a division number deciding means, a function value calculating means, a section distance calculating means and an operating amount output mean...
We know that once the person stops pushing, friction will bring the package to rest. In terms of energy, friction does negative work until it has removed all of the package’s kinetic energy. The work done by friction is the force of friction times the distance traveled times the cosine o...

Work is said to be done when a force (push or pull) applied to an object causes a displacement of the object. We define the capacity to do the work as energy. Power is the work done per unit of time. This article discusses work, energy and power in detail. Table of Contents What ...
Potential Energy b W F dr U(r ) U(r ) U b a a • The work done by a conservative force can be represented in terms of the change in potential energy. The potential energy U is the energy associated with the configuration of ...
