A list of things that work better when there is less friction?
Ice skating: Less friction allows for smoother gliding on the ice. Aerodynamics: Reduced friction helps vehicles like airplanes move more efficiently through the air. Roller coasters: Less friction between the wheels and the track allows for faster, more thrilling rides. Bearings: Reduced friction in bearings enables smoother movement in machinery and devices.
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.
How can reducing friction make a pulley work better?
Reducing friction on a pulley can make it work better by allowing the system to move more smoothly and efficiently. This results in less energy being wasted as heat and more of the input energy being used to lift or move objects. Additionally, it can reduce wear and tear on the pulley system, extending its lifespan.
Why would machines work better without friction?
Machines work better without friction because it reduces wear and tear on moving parts, lowers energy consumption, and minimizes heat generation. Friction can also cause noise and vibration, which can negatively impact the performance and lifespan of a machine.
What causes the output work of a machine to e less than the input work?
Some of the input force is lost due to friction. If you are using a pulley system then there is friction between the rope and the pulley and there is also friction within the ball bearings of the pulley itself. If you are using an inclined plane there is friction between the plane and the object traveling upon it. In a friction-less world the input is equal to the output.
Can you work on friction less floor?
No, We cannot do work on friction less surface
Why optimization is used?
Optimization is used to make things work better. This may include making things use less resources, work faster, or do their job better.

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.
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.

Why is it to stop a car on a wet road?
it is harder because there is less friction with lubrication -which is what water is -and you need friction for the breaks to work

Why is always work output less than work input?
Work output is always less than work input because some work is lost to friction and heat which is created in the process of physics.

Does the simple machine reduce overall work needed?
No. Work out is always less than work in due to friction and other losses..
