Can static frication do nonzero work on an object?if yes give an example. If no,give reason. |

Answer» Thank you In limiting friction body does not gain displacementso work done zero Static friction is a non-conservative force, and therefore has no associated potential energy. When static friction is internal, however, it is a non-dissipative force, performing zero net work on the chosen system. The reason is that static friction guarantees that the two interacting objects will undergo the same displacement. Thus, the work done on the two objects will cancel by Newton\'s Third Law. |
