What can cause loss of energy?
According to the laws of thermodynamics, energy can never be "lost" or "made". Energy, in a closed system, is always constant. Energy can however be "lost" to the environment, for instance by friction. If you drag a box over the floor, some of the energy you are putting into moving the box is being "lost" to the environment by friction between the box and the ground (and a very small amount to air friction). You could therefor say that friction is a cause for "loss" of energy.
How does friction affect energy transformations?
It cause degradation of energy transformation. In other word, it loss the efficiency through friction.
Why is friction a disadvantage?
Loss of energy. Any way friction is a necessary evil
How does friction affect perpetual motion machines?
IN SIMPLE WORDS: Friction turns mechanical energy into heat energy which causes a loss in mechanical energy and loss in possibility to continue motion..
What force stops manchines from being 100 percent efficient?
Reducing its temp. heat is the most common form of energy, and when a machine has friction, it is creating heat. by reducing the amount of friction, maybe by using some kind of lubricant between the objects, it will create less heat and thus use less energy input, with a higher input to out put ratio.
Why does friction reduce the efficiency of machines?
Friction requires energy to overcome it. This causes loss of energy in the system. Loss of energy in a system, by definition, is a reduction of efficiency.

What type of energy that is lost doing work is lost as what type of energy?
Usually thermal energy. This is true for all types of heat engines, ie gasoline or diesel engines, gas turbines, steam turbines, and so on. If you are talking about mechanical work like a system of levers, or pushing a weight along a surface, friction will be the cause of energy loss and this again will show as thermal energy loss (heat is produced at the points of friction)

What does loss of energy by friction end up as?
Heat.
What is form friction?
loss of energy in fluid because of friction of seperated boundary layers

What effect does friction have on a machines efficiency?
Efficiency of the machine is reduced due to loss of energy by friction.
Decreases efficiency by causing an energy loss to the environment.?
Friction
Why do elbows cause more friction loss in ductwork?
Elbows cause more friction loss in ductwork because elbows create resistance in the natural flow pattern of the air stream
