A 2.3-kg block slides down a plane (inclined at 43degrees with the horizontal) at a constant speed of 3.3 m/s. At what rate is the frictional force doing work on the block?
The work done by friction is the amount of energy that is converted into heat as a result of two surfaces rubbing against each other.
The work done by friction is calculated by multiplying the force of friction by the distance over which the force is applied.
The amount of work done by friction is affected by the roughness of the surfaces, the force of the applied pressure, and the speed at which the surfaces are moving.
No, friction can also result in negative work, meaning that it decreases the total energy of the system.
The work done by friction can decrease the efficiency of machines by converting some of the input energy into heat, which is not useful for performing work.
