In the reference frame of the interface between two surfaces, static friction does Zero work, because there is never displacement between the surfaces. But it can be positive , negetive or zero with respect to choosen frame of reference.

Do all forces of an object cause work to be done?
No, work is only done by a force when there is displacement in the direction of the force. Forces that do not cause any displacement, such as static friction or normal force, do not do work on an object.
Is friction produced when work is done?
Yes, friction is produced when work is done. When two surfaces rub against each other, heat is generated due to the resistance caused by friction. This results in the conversion of some of the work done into thermal energy.
Can work be done by friction?
Yes, work can be done by friction. When an object moves against a surface due to friction, work is done to overcome the resistance offered by the frictional force. This work results in heat production and can cause the object to experience a change in its kinetic energy.
If the force applied to an object doesnt make the object move then no friction has been done is this true?
No, it is not true. Friction can still occur even if the object does not move. The force applied may overcome static friction but not cause the object to move due to other factors like weight or surface roughness.
What happens to work done by friction if the speed doubles?
If the speed doubles, the work done by friction remains the same. Friction depends on the force between surfaces and the distance they move relative to each other, not the speed.

What is friction and how does it affect work done?
Friction is the force that opposes the motion of an object when it is in contact with another surface. It affects the work done by causing energy to be lost as heat, which reduces the efficiency of a system. More friction means more energy is needed to overcome it, resulting in more work being done.
Is it easier to lift a 50 kilogram box straight up 8 meters or slide it up an inclined plane that is 20 meters long?
While lifting it straight up is harder, overall it is less work because you do not have to contend with the friction of the inclined plane. Overcoming that friction is work done which is totally wasted.While lifting it straight up is harder, overall it is less work because you do not have to contend with the friction of the inclined plane.

When a force moves objects over a rough horizontal surface at a constant velocity the work done against friction must?
When a force moves objects over a rough horizontal surface at a constant velocity, the work done against friction must be equal to the work done by the applied force to maintain the constant velocity. This is because the force of friction opposes the motion of the object, so the work done by the applied force must overcome the work done by friction to keep the object moving at a constant speed.
How does the output work done by machine change when friction is reduced?
Increases
Work done against gravity work done against friction?
The work done against gravity is given by the force applied multiplied by the vertical distance lifted. The work done against friction is given by the force applied multiplied by the horizontal distance over which the object moves against the force of friction. Both types of work involve overcoming resistive forces to move an object.
How much work did the movers do horizontally pushing a 150 kg crate 10.4 m across a rough floor without acceleration if the effective coefficient of friction was 0.70?
The work done by the movers can be calculated using the work-energy principle. The work done can be found by multiplying the force of friction by the distance the crate was moved. The force of friction is the product of the coefficient of friction and the normal force (weight of the crate). The work done will be equal to the force of friction multiplied by the distance moved.
What friction is a form of kinetic friction?
i don't know. if its your home work to be done yourself =(. if it isn't good because its a sign of curiosity = )
