Difference between conservative and non conservative forces |
| Answer» \tConservative forceNon-conservative forceA force is said to be conservative if the work done by or against force is dependent only on the initial and the final position of the body and not on the path followed by the body.A force is said to be non-conservative if the work done by or against the force is dependent on the path followed by the body.Work done by the conservative force in a closed path is zero.Work done by the non-conservative force in a closed path is not zero.Eg: Gravitational force, magnetic force, electrostatic force, etcEg: friction, viscous force, induction force in cyclotron, etc.\t | |

What is the characteristics of uniform motion |
| Answer» If a body is performing uniform motion in a circular path then1) its speed will remain constant, ie.,it will not change with time.2) magnitude of Velocity will also remain constant but it\'s direction changes . Since Velocity is a vector quantity which depend upon both its magnitude and direction so,Velocity of body changes.3) acceleration also changes because its Velocity changes and acceleration depend upon Velocity of the body. | |
