When would you want less friction?

Answer 1

There are many applications that would benefit from less friction. Any kind of motion where heat is produced but not intended would benefit from less friction.

Some examples:

1. the contact point between the piston and wall in an engine produces less heat and more power with less friction

2. air flow over a car's exterior, over a plane's exterior, over a rockets exterior results in reduced drag (air resistance) with less friction

3. the space shuttle could definitely use less friction with the atmosphere during re-rentry

4. electrical conductors are more efficient as friction decreases

5. if friction were 0, the perpetual motion machine would be possible

Answer 2

Less friction would be desirable in situations where you want to increase speed or efficiency, such as reducing energy consumption in machinery, improving the performance of a vehicle, or allowing objects to move more smoothly past each other. It can also be beneficial in situations where friction may cause wear and tear on surfaces, like in medical devices or precision instruments.
