What else can I help you with?
Is the efficiency of a machine is 60 the percentage of work input used to overcome friction?
No, efficiency of a machine is a measure of how well input energy is converted into useful output work, and is calculated as useful work output divided by total work input. The percentage of work input used to overcome friction would be related to the frictional losses in the machine, not the overall efficiency.
Does friction waste more work on a longer or short?
Friction wastes more work on longer distances due to the increased surface contact and the higher energy required to overcome it. Shorter distances have less surface contact and require less energy input to overcome friction.
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.
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.
Does friction waste more work on longer or shorter planes?
Friction will waste more work on longer planes because the force of friction acts against the direction of motion for a longer period of time. This results in more work being done to overcome friction and move the object along the longer plane.
Why is part of work output is used to overcome friction?
In any type of movement there is friction. This must be accounted for.
Why is the work output of a machine never to the work input?
Some work input is used to overcome friction.
Why is the work output of a machin never equal to the work input?
Some work input is used to overcome friction.
When a machine drills holes in metal some of the work input is used to overcome what?
Friction :) it says so in in my science book.

How it is friction related with work?
Work = Force x Distance Friction is a force usually operating in the opposite direction to the force being applied. Thus friction adds to the size of the force applied and work is increased.
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.
