What are conservative force , non - conservative force , conservative field and non - conservative field ? |
|
Answer» Solution :Conservative force : A force is said to be conservative if the work done by the force on a body is path INDEPENDENT and depends only on the intial and final POSITIONS . Such FIELD is known as conservation field . For EXAMPLE , gravitational force , electric forces and magnetic forces . Non - conservative forces : A force is saidto be non conservative if the work done by the force on a body is path dependent. The work done by such a force in moving a body arounda closed path is not zero . Such field is known as non - conservative field . For example , frictional and viscous froce . |
