Friction In Moving Bodies

Assertion : Work done by orforce of friction in moving a body through any round trip is zero. Reason : Because friction is a conservative force.

Statement-1 : Friction is non-conservation force. Statement-2 : This is because work done against friction, in moving a body over a closed path, is never zero.

The work done against friction in moving a body from A to B is 200 J. If the body is again brought back to A along the same path, the total work done for the trip against friction is

Assertion: Work done by the force of friction in moving a body around a closed loop is zero. Reason: Work done does not depend upon the nature of force.

Assertion: Work done by the force of friction in moving a body around a closed loop is zero. Reason: Work done does not depend upon the nature of force.

A body moving on ground with a velocity of 14 m//s comes to rest due to friction after moving ove a distance of 50 m. Detennine the co-efficient of friction between the body and the ground.

Do fluids offer force of friction on bodies moving through them? Yes/No.

Work done by friction on a body moving on plain ground ……………
