Mechanical Energy

Content Provider AK Lectures
Description If we consider our system to be a conservative system, then only conservative forces (such as gravity) are acting on our object in the system. If only conservative forces are acting on our object, then the total mechanical energy of the system is conserved (remains constant). Usually the total mechanical energy refers to the sum of the kinetic and potential energy of the object. If our object moves from some initial position to some final position, then the initial sum of the kinetic and potential energy always equals the sum of the final kinetic and potential energy. This is known as the conservation of mechanical energy and is true as long as only conservative forces are acting on our object. The equation that is a result of the conservation of mechanical energy can be very useful when solving problems, as described in this lecture.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
