How does the friction between the parts of a machine affect the work input and work output?
Friction between the parts of a machine decreases the work output by converting some of the input energy into heat. This results in inefficiencies and reduces the overall performance of the machine. To compensate for the energy loss due to friction, more work input is required to achieve the desired work output.
The amount of work done on a machine is 300 j and the machine does 50 j of work. what can you say about the amount of friction that the machine has while operating?
The machine has 250 J of work due to friction because the work done on the machine (300 J) is greater than the work output by the machine (50 J). This indicates that friction is opposing the motion of the machine and causing energy loss.
How does lubricating a machine affect the output work from that machine?
Lubricating a machine reduces friction between its moving parts, allowing them to move more freely and smoothly. This can result in improved efficiency and reduced wear and tear on the machine, ultimately leading to increased output work by maintaining optimal functioning of the machine.
Friction is not related to the efficiency of a machine true?
False. Friction can significantly affect the efficiency of a machine by causing energy losses and reducing its overall performance. Minimizing friction through proper lubrication and design can help improve the efficiency of a machine.
Besides a reduction in friction the only way to increase the amount of work output of a machine is to the work input.?
Increasing the work input to a machine is a way to enhance its work output beyond minimizing friction. By supplying more energy to the machine, it can perform more work. This principle follows the law of conservation of energy, where the work input equals the work output plus any energy losses due to factors like friction.

Does a machine do less work when friction in a machine increases?
Yes. Since more work goes to counter the friction force, less work goes to do the actual function of the machine.

How does work affect friction?
work is movement, and all movement causes friction, since there is no such thing as a "perfect" or "100% efficient" tool yet.

How does the output work done by machine change when friction is reduced?
Increases
Why is the work output of a machine never to the work input?
Some work input is used to overcome friction.

This principle follows the law of conservation of energy, where the work input equals the work output plus any energy losses due to factors like friction.
In any machine some work is wasted overcoming what?
In any machine, some work is wasted overcoming friction, which is the resistance caused by the rubbing of one object against another. This friction generates heat and sound, ultimately leading to a loss of energy efficiency in the machine. Minimizing friction through lubrication and proper maintenance helps reduce this wasted work.
Is it true that every machine uses some of its work input to overcome friction?
Yes, it is true that almost every machine uses some of its work input to overcome friction. Friction is a force that opposes motion and can cause energy losses in a system, which often results in the need for extra work input to maintain operation. Reducing friction through lubrication or design improvements can help optimize machine efficiency.
When using a real machine to do work input work will always be?
When using a real machine to do work, input work will always be greater than the output work due to the presence of factors such as friction, heat loss, and inefficiencies in the machine. This difference in work is known as the machine's efficiency, which is a measure of how well the machine converts input work into useful output work.
