Friction is not related to the efficiency of a machine true?

false


Is Friction is always undesirable true or false?

No You need friction to Walk, So the Answer Is False


Friction changes the useful work of a machine into mechanical energy true or false?

true


What happens to the mechanical advantage of a machine if friction is reduced through the use of oil or some other means?

Wear and tear of moving parts would be reduced. Less energy would be needed to run the machine, as there would be less friction to be overcome. A well lubricated machine is more efficient than a neglected machine with unoiled parts.


When an object rolls over a surface the kind of friction that occurred is called round friction True or false?

false it is rolling friction


True or false when an object rolls over a surface the kind of friction that occurs is called round friction?

True or false the force needed to overcome kenetiic friction is useally greater than that needed to overcome static friction?

false; usually it takes more force to overcome static friction which is higher


The force needed to overcome static friction is usually less than that needed to overcome kinetic friction?

true


Air resistance is the opposite of from friction true or false?

False. Air resistance is friction. A meteor coming in from space hits our atmosphere and glows brightly due to the airs friction.
