Losses due to friction mean that in a closed system there is never 100% transfer of energy and therefore no such thing as Perpetual Motion machines (although some get close).

Advantages of friction a necessary evil?
A necessary evil means that friction has advantages as well as disadvantages so it called as necessary evil. Advantages of friction areits helps us to walkto writedriving car, etc,
What is the Disadvantages of Friction?
firction stops the movement of the object.it opposes the motion of an object.for eg, if u throw a ball on a frictionless surface,it will never stop. more the friction more is the pressure u need to apply to do some work
What are the 2kinds of friction?
Static Friction and Kinetic Friction. Static Friction is what friction that slows you down. While Kinetic friction is sliding friction.
What do lubricants do to friction by replacing sliding friction with fluid friction?
Lubricants reduce friction by replacing sliding friction with fluid friction.
Which force is weakened when the floor is wet?
Friction is reduced on a wet floor.
Photos of advantages and disadvantages of friction?
Advantage of friction photo
What are the disadvantages of a crankshaft?
it arise friction
What is the advantages and disadvantages of dry friction?
frictionlaws of a dry
What are the advantages and disadvantages of having friction in sport?
These are a few of the great many advantages and disadvantages of having friction in sport: Friction allows a running person to stop, change direction, jump, catch a ball, and throw a ball. Friction between a ball and the air limits how far it can be thrown (although gravity has an even greater effect). Runners require energy to overcome the friction between their feet and the ground.
Friction is inveitable but it has disadvantages why?
Friction is a force that must be overcome for no useful purpose. It takes energy to do this, and thus is wasteful.
What are the other disadvantages of force?
friction can cause the wearing away of surfaces
Why friction is a necessary evil?
because we cant walk , hold articles , we cant write and the construction of house is impossible. but there are some disadvantages in friction.
Advantages of friction a necessary evil?
A necessary evil means that friction has advantages as well as disadvantages so it called as necessary evil. Advantages of friction areits helps us to walkto writedriving car, etc,
What are the advantages and disadvantages of friction piles in construction?
1) In machines the mechanical parts which rub with each other wear out. 2) Due to friction between the sole of the shoe and the floor the sole wears out. 3) Tyres of vehicles wear out because of friction. 4) Energy is wasted in overcoming the force of friction.
What are disadvantages of heat produced by friction in machines?
energy used for the machine will get lost as heat .machine parts will get worn out.
What are disadvantages of friction with examples?
Friction produces unnecessary heat leading to the wastage of energy.The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects.Forest fires are caused due to the friction between tree branches.A lot of money goes into preventing friction and the usual wear and tear caused by it by using techniques like greasing and oiling.
Describe 3 examples where low friction is not useful?
Friction is very useful but it has its own disadvantages. Friction causes wear and tear. Friction spoils the soles of our shoes. friction reduces speed This is all wrong some not useful types of friction are are when airplanes fly the friction causes heat that materials that will withstand which are costly.
