All energy ultimately ends up as heat, thus, all physical processes' ultimate 'waste' products is heat Friction always creates heat, and an increase in friction always creates an increase in (waste) heat...remember Second Law of Thermodynamics, right? Thus: Friction increase increases heat; increases waste and thereby decreases efficiency, without even considering the damage that the increased heat can create

When a body slides over a surface the kinetic friction and static friction related as?
Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.
Is rolling friction greater than sliding friction?
Typically not. However rolling friction is somewhat of a myth. Rolling friction is actually caused by static friction. There are really only two types of friction: Static and Kinetic. That's it! Rolling friction is caused by static friction and the coefficient of friction (which determines its strength) is dependent upon the two materials of interaction.
What is the advantages of friction?
what is the advantages of friction
How can wildfires cause damage?
A fire starts by friction or by an electric spark igniting the gasses or general fuel used.
Is friction a natural force?
friction is a natural force
Do tornadoes have friction?
Yes. Friction is always a factor. It is partly through drag, which can be thought of as friction, that the wind in a tornado is able to cause damage.
What friction do to materials?
Friction can damage materials,slice,and make things move because when you touch, rub or move these things we create friction.
What is friction skin damage?
Friction skin damage is basically a rug burn. When your skin is rubbed against something else and it peals off the very first layer of skin.
Why do you lubricate surface with oil?
Usually to reduce friction and/or to remove heat from the surface to prevent damage by friction and/or heat.
Why it is important for you to reduce friction on compound machine?
Because too much friction can damage the simple machines that make up the compound machine.
The function of the fluid that fills the pericardial sac is to decrease what?
Friction around the heart and possible damage.
Why does your throat hurt after pitching a real high note?
The vibrations of the throat cause friction and damage cells.
How do you get a blister?
Friction and Burning are the main culprits. The body forms a blister to protect the underlying skin from more damage.
What are the differences between useful and harmful friction?
The type of friction that benefits in some or other way like smooth running of vehicles on the road is called Useful Friction whereas other wherein it becomes a causative factor for wear and tear or damage to the object in question.
What is another way to reduce friction?
Friction can cause a lot of damage on rough surfaces. Friction also reduces the efficiency of mechanisms and releases heat that can damage parts, so we often want to minimize its effects by reducing the surface areas that are in contact or using a lubricant such as, oil, grease, and graphite.
Why do motors use oil and grease?
For lubrication. To reduce friction and heat buildup which would quickly damage the engine otherwise.
Is it true that lubrication in vehicles moving parts prevents damage from heat and friction and keeps the moving parts operating efficiently?
yes
