Work done by static friction is alway?
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.
Is the work done by friction always negative?
No, the work done by friction can be either positive or negative, depending on the direction of the force and the displacement of the object.
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.
Can workdone by friction be positive?
No, work done by friction is always negative because it opposes the direction of motion. Friction always acts in the opposite direction to the force causing the object to move, resulting in a loss of energy and a decrease in the total mechanical energy of the system.
How do you remove the static charge?
Static charges can be removed by earthing. Since only negative charges can flow the earth takes in infinite number of electrons. This same principal is applied to a lightening conductor since lighting is nothing but the flow of electrons formed due to friction of two clouds.

What is the formula for calculating the work done by friction?
The formula for calculating the work done by friction is: Work Force of friction x Distance.
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.
How can one determine the work done by friction in a given scenario?
To determine the work done by friction in a scenario, you can calculate the force of friction acting on an object and multiply it by the distance the object moves in the direction of the frictional force. This will give you the work done by friction in that scenario.
How to calculate the work done by friction in a given system?
To calculate the work done by friction in a system, you can use the formula: Work Force of friction x Distance. First, determine the force of friction acting on the object. Then, multiply this force by the distance the object moves against the frictional force. This will give you the work done by friction in the system.
How friction can be a nuisance?
Friction can be a nuisance when it causes wear and tear -- on parts in machinery, on items of clothing, furniture, etc. Friction can also be a nuisance when it causes static electricity. The static electricity, depending on the circumstances, can cause anything from a mild shock and clothing cling to an explosion at a gas pump or near gas fumes in a building. It can also cause damage while work is being done on the insides of a computer.
What can be done to prevent ARP spoofing?

Is friction is a foe?
Friction can be a friend when walking and when driving a car. For example, walking or driving on ice can be very risky due to the lack of friction. Friction can be a foe when it causes more work to have to be done or excess heating. Friction is responsible for our getting blisters on our hands or feet.
