What is friction and what are two types?
Friction is the force that opposes the motion. It is the force between two surfaces rubbing together. Actually there are three kinds of friction:static friction - friction occurs at rest. It is also the strongest type of friction.kinetic friction - friction that occurs when an object is in motion.rolling friction - the weakest of all the three.So that's the basic definition of friction and its kind.add Commonly, the status of the friction alternates between static and sliding many times per second. Commonly called 'slip stick' friction. This is the cause of a squeaky door hinge, the crunch of snow, and even if some remarkable 'singing sands' in some deserts.[Alongside a squeaky door hinge you'll often find a deposit of fine dark powder - this is iron dust - some of the iron actually torn off the hinge surface in moving between these two frictions. ]
How does lubricant reduce the force of friction between hinges in a door?
It reduces the coefficient of friction.
Is a hinge on a door an example of a wedge?
No.
Name three effects that can be caused by friction?
The squeaky door sound is caused by slip - stick friction, so sound is one effect. The black powder debris near a door hinge is the ground particles from the door hing, wearing the metal away. The Brake drums on your car will generate heat as a result of the forward energy of the car being converted to heat as you brake.
What are the 3 ways of decreasing the friction?
Decreasing friction:- add a lubricant (like oil in a door hinge)- rolling objects (e.g. rollerblades)- streamlining (like making an aircraft a special shape to reduce wind resistance)Source(s):I have a good memory and listen in school
What is the kind of friction that exist between oil and a door hinge?
Im Pretty Sure Its Fluid Friction??? ;)

Does the door hinge adjust where the hinge is attached to the hinge post?
door hinges attached to door and hinge post
Why will you need to apply grease when the hinges on the door creaks?
Because the 'creak' is the result of friction generated by the hinge parts moving. Grease or oil deposits a thin film of lubricant between the surfaces, preventing friction (and thus the creak) happening.
What is the name for pin that slides into a door hinge?
door hinge pin
Why does nothing rhyme with orange?
Bro, DOOR-HINGE. Door-hinge rhymes with Orange.
How does lubricant reduce the force of friction between hinges in a door?
It reduces the coefficient of friction.
How do you keep an interior door from closing by itself in a house?
The very easiest way is this: # Remove the middle hinge pin. (bottom hinge pin if you only have two hinges) # Set it on a concrete sidewalk, driveway etc. laying flat. # Hit it with a hammer in the middle. This will bend the pin slightly, causing friction in the hinge and, once put back in the hinge, it should hold the door in any position you open it to.
What is door hinge?
A door which hangs on hinges. The hinge is what allows a door to open and close and is made of metal, attached to the door by bolts or screws.
Can you use a word hinge in a sentence?
The hinge of the door is loose.
How do you use hinge in a sentence?
Perry Mason's entire case will hinge upon this very point. The door will not swing without a hinge.
Why is hinge theorem called hinge theorem?
because it works like a door hinge. When the door hinge is opened wider the angle is greater and when opened less the angle would be lesser.
